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.
