Manipulatives Blog
1. How do you hold every student accountable?
Using manipulatives to support mathematical teaching can be incredibly effective. To manage student accountability, I think that teachers should make sure that the different types of manipulatives are introduced. This way students have the opportunity to learn how to use the manipulatives correctly and apply the different manipulatives to their concept skills. Another way I think that students can be held accountable with manipulatives is through allowing students to freely explore and use the manipulatives during a free period or down time during a learning center. By allowing students free access to different manipulatives, students will feel more comfortable with the material during class time. Another way to manage manipulatives during class time would be to assign a group leader to the table to ‘manage’ the manipulative tools. Dividing roles in groups helps to give each individual child a role during instruction. By giving each child a role, they are held accountable to both their group and themselves.
Manipulatives are sometimes viewed negatively when they are viewed as ‘playing materials.’ In a sense, I completely disagree with playing being a negative concept with manipulatives. Children love to play and explore. In a journal article I read earlier this semester, a sand play table was used in a classroom. Children were able to go ‘play’ at the sand table and communicate with their friends (incorporation of process standards). Once the students became comfortable with the table and the communication at the table, the teacher would introduce new material to the table to go along with concepts he/she was teaching. For example, the teacher would put different sized beakers in the area with the sand. The teacher would allow the students to first explore the new objects through play and communication. Eventually, the teacher noticed that the students would compare the different amounts of sand that each type of beaker could hold. Students began to explore mathematical concepts on their own. As the students played at the table, they began to question certain math concepts. The teacher slowly but surely would go to the play table and pose questions to the students and listen to their reasoning (another process standard). Concepts were explored through a simple station where children were able to play and communicate. I believe manipulatives should be used this way. Students need the ability to play, explore, and communicate. Eventually, students begin to question which leads them to a more exciting role in the math learning process. Teachers can then guide the students with questions or comments regarding the students’ questions. Eventually concepts are constructed and developed over time. Process standards are incorporated naturally into this process.
2. Why not “hands-on”, why is it “hands-on, minds-on?”
When students become engaged in the manipulatives they are working with, they are stimulating their minds. Rather than just playing with blocks at a table, students are communicating and manipulating materials. Students naturally begin to question ideas on their own through this process. However, if good instruction is provided before the introduction of manipulatives, students can then use the manipulatives to enhance the instruction. If students have been learning about fractions in the classroom and then pattern blocks are used as an exploration manipulative, students will begin to apply their learning to the manipulatives. Students will start to question, “I wonder how many triangles will fit into a hexagon.” Students then work and communicate with each other and construct their concepts in a more concrete manor. Manipulatives are not going to save mathematics. Teaching still needs to be effective and teachers need to stimulate interest in the subject and show real-life application. When students have strong instruction, they can succeed in the use of manipulatives. Students will build onto the foundation through exploration. This is where students being to use “hands-on, minds-on.” When students use manipulatives in this way, they will only strengthen abstract math concepts into more concrete representations.
When students have choice and control in the manipulatives that they use, students can apply reasoning and proof to show how that specific manipulative was used to deepen the understanding of an abstract idea into a concrete representation. Manipulatives and representation work cohesively. Using concrete representations of abstract mathematical concepts and ideas helps students to see where the idea or abstract material becomes a concrete concept that they understand with meaning. Manipulatives shift students’ thinking from basic memorization of rules and facts and more into concept construction. When students get to use manipulatives, they deepen their understanding of specific concepts. The more representation methods that the children can apply using the manipulatives, the more constructed these concepts will be shown through the students. Students also get to use communication and problem solving as they work through using different manipulatives. As teachers, we need to give up some of the control with students and allow them to explore more freely. By doing this, students learn to think on their own and build onto prior knowledge to create a foundation for greater concepts. Instead of the teacher being viewed as the ‘experts,’ the students begin to think they are the experts. When they take responsibility for their own learning and become engaged through the use of manipulatives, educational concepts can be constructed at greater levels. Connections can also be made through the use of different subjects such as art. When students learn concepts in mathematics such as slides, flips, rotations, etc. students can create tessellations. Tessellations can be viewed as both artistic and mathematical. When we use manipulatives for content material such as slides, flips, rotations, turns, etc., students can visually see the concept as well and physically manipulate the object through exploration.

Errors Blog
Going through the math errors document was probably my favorite and most beneficial activity this semester. When working through numerous types of mathematics concepts, it is really interesting to see how some students make mistakes. I had never imagined teachers actually sitting and looking at an error to see where a student made a mistake; however, I found it to be fascinating to see the ways in which some students logically think and apply methods that do not work for specific problems. When teachers take the time to look at how the student made the error, they can begin to see where a specific student needs some additional guidance. Students often are taught the formulas or told ‘this is just how you do it,’ which does not enforce any core concepts. Going through the errors enforced why the process standards are so important. When the content standards are appropriately used in the classroom, students are able to see concepts in more depth. Instead of just working though problems, students understand the meaning behind the problems and are less likely to make errors such as the ones presented. Instead of the student focusing on the ‘rule’ or ‘formula,’ they can recall how to do the problem through reasoning and proof. Students then are less likely to use incorrect rules or short cuts to simply solve the problem.
Learning different methods for teaching subtraction, additions, multiplication, division, and using fractions is something that was specifically beneficial to me. Growing up I learned the formulas and did not learn meaning behind the formulas. When I try to recall when one fraction is bigger or smaller than another, I often get confused. Learning to visualize fractions as portions of a whole is crucial. Students in younger grades often have a hard time determining which fraction is bigger or smaller and how to add, subtract, multiply, and divide them. Learning the meaning behind these concepts and using models to help students visualize these concepts is definitely reinforcing.
Looking for patterns in student errors and putting meaning behind the errors can help teachers focus on areas in which students are having difficulties. When we realize the mistakes the students are making, we can help address the problem and put more emphasis to the meaning of the mathematics concept. Teachers can help students put an end to misunderstandings when they realize the pattern behind the error.

April Journal Article MTMS
Students need spatial sense and understanding when using two-dimentional shapes and three-dimentional diagrams. Sometimes, students experience difficulties with spatial understanding becaues it is not intuitive. Students need practice visualizing two-dimentional nets and their transformations to three-dimentional figures. In order to help students understand how shapes are creating through folding, curling, etc. to a net, teachers often use geometry technology software. One teacher used a triangular pyramid and a cube and asked the students to create the nets to these figures. Using Geometer's Sketchpad, the teacher showed the students how to construct a net and modeled construction as well as use of the Sketchpad. Students were then able to explore and create their own net to try to figure out the net for the solids she presented earlier. Another approach the teacher took to developing spatial understanding was to pass out congruent three-dimentional pieces of a shape and had her students try to develop the net for a specific figure. Students often started solving this problem by using a square out of the pieces given to them in order to start building their net. Students were able to see that by creating two identical pieces from equilateral triangles into the form of a trapezoid, that they could construct a tetrahedron from these two 3-D figures.
Working with students to help them develop spatial understanding between 2-D and 3-D shapes will benefit them in their understanding of geometry. By having this type of understanding as teachers, we will better be able to use hands-on activities to teach our own students how to better comprehend spatial sense and how it applies to different forms of geometry. When students use inquiry based learning such as the type given in this lesson, students get to explore different nets and models as well as incorporate technology into the curriculum. This overall will help students to develop spatial sense.

Co-teaching is a specific type of teaching where a special education teacher and a classroom teacher work collaboratively in order to develop a more cohesive progam for planning, teaching, and assessing/evaluating. By using collaborative efforts such as co-teaching, the classroom becomes unified and represented as a whole unit. In one specific classroom, a classroom teacher and special education teacher taught mathematics together. The classroom teacher would teach her mathematic concepts or lesson while the special education teacher would ask her to clarify specific points or to repeat important concepts that may need to be heard again. By doing this, the two teachers incorporate a strategy similar to the reading strategy, think-alouds. These two teachers also take turns teaching important concepts and share the role of instructing in the classroom such as a team-teaching role would present. By doing this, students are gaining a deeper understanding of difficult concepts. By repeating difficult material and clarifying it in different ways, students get to see different aspects of the problem. The article lists a number of different models for teaching a classroom of integrated learners; these include:
Team: shared role between the two teachers
Alternative:
- one teacher works with small groups for re-teaching, enrichment, pre-teaching, etc. while the other teacher works with the rest of the class
- teachers use think-alouds to clarify and to help train special needs students to work through the problems rather than applying a random formula or idea that they have learned; (lack of metacognitive skills)
- great for hands-on learning
- great for working one-on-on or in small groups to clarify concepts for struggling learners
One teach, one assist:
- allows one teacher to teach while the other teacher walks around and observes and helps students who need it
- can beneift students with behavior issues
- helps to focus more on special needs students; gifted learners, special needs, ELL
- allows individual assistance for students
- great way to monitor progress
Stations:
- content is divided into different stations and each teacher teaches a specific station
- great way to incorporate the NCTM standards
- teachers can focus on an area of their strength to benefit deeper understanding for students
- stations often incorporate real-life integration
- allows for monitoring and reinforcement
- can help prevent math anxieties early on
Parallel:
- the teachers plan cohesively but then each teacher teaches a half of the entire class
- teachers must plan for all areas of learners
- teachers must think about how all students learn and how to relate to all students
As a teacher, co-teaching would be something that would be benefical in the classroom. It provides rich learning experiences for all areas of learners. During these types of instruction mentioned in the article, teachers use models and clarification so that all students have the ability to understand concepts. Co-teaching helps create a common instructional language that all areas of learners can understand. This helps to unify the classroom and help students become more engaged in the materia. C0-teaching provides a rich learning opportunity for a wide-variety of students. The talents and energies of two teachers can be effective in a class of different types and styled learners.
