Who Wants Pizza? A fun way to learn about fractions.
Grades 3-5
This applet is laid out in a very organized manor. Students can easily explore an introduction to fractions, different methods for using fractions, and practice fractions (addition, equal, subtraction, multiplication). The ease of use of this applet is fairly simple. The organization of the applet is laid out nicely and the practice problems show both visualizations of the parts in comparison to the whole. Children can easily practice their knowledge after reading about the type of fraction use they are interested in. The description for using the fractions for different methods is also very descriptive and shows visualizations to clarify word meaning. At the end of each online section there is a place where students can test their knowledge and submit their answers to see if they were correct. There is also a bonus question at the bottom that helps children think more critically. Students are able to view the correct answer after they have thought about the problem. Overall, this applet can be as challenging as the student or teacher wants to make it. Students can explore different avenues of fractions (addition, subtraction, multiplication, etc.) which gives them different options for practice and challenges.
I believe that students would find valuable learning in this math applet for numerous reasons. As I went through the math applet, it was refreshing to have the information laid out in both words and pictures. Through description using visual fraction bars with individual boxes colored in to represent part(s) of a whole unit, students can easily see how different parts relate to a whole unit. This idea can be challenging for students to understand, and I think that this applet gives a great understanding to the part-whole relationship. This applet also gives a valuable assessment for the students because it provides them with practice questions and an opportunity to submit their answers at the end of their practice. Students get to use the mouse to shade in different fractions that the applet asks for. Through use of the computer and visual aids, students get to investigate fractions and work through their learning on their own. I think that this specific applet provides students with a lot of benefits for learning. Students are able to explore the concepts of different avenues of fractions on their own. They can pace themselves and can work on different areas that they find interesting or a struggle. Students also get to practice their knowledge of fractions through the computer assessment provided. A weakness that this applet has is that students might get carried away with the different amount of options provided. If students have not yet worked with multiplication with fractions, they might want to click on it in advance and it may confuse them. However, this could also provide students with the opportunity to explore different avenues of fractions. The information provided would give them a good basis for beginning exploration on different fraction uses. I liked that the students could relate the fraction use to real-life food situations; which students would love. This applet also provides the teachers with a teacher's page which shows how students can use the strategies in the applets to build upon fraction concepts. The grids provided in the applet can be printed out and used in congruence with the activity as well as be used in part for an assessment. This teacher's page also describes the use of how this applet coincides with the NCTM standards for 3-5th grade students. Overall I found this applet very user-friendly and educational in the use of fractions.

Pythagorean Theorem Math Applet
grades 6-8
This applet is very user friendly and is to the point and is clear and concise. Basically, students get to explore the Pythagorean Theorem through the use of an interactive figure with two little squares, a triangle, and a bigger square. Each of the two little squares are shaded a color. These little squares can be moved through the click of the mouse to fit into the bigger square. This shows how the different legs of the triangle end up creating the actual symbolic representation of the Pythagorean theorem a^2+b^2=c^2. Students get to use the visualization in order to examine and describe how the relationship in the diagram represents the actual Pythagorean Theorem. Overall this is a very basic applet provided by the NCTM which aligns with student objectives and shows a basic, clear description of the Pythagorean Theorem.
Student learning in this applet is a little less guided than the previous applet described above. This applet is for grades 6-8 and is a little more based on inquiry learning. Students have more of an opportunity in this applet for exploration and learning through their own exploration with minimal guidance. Guided questions are posed so that students can answer them as they use the actual applet. This will help guide them to their overall answer at the end of the exploration process. Students are presented with more inquiry based questions asking them to explore if the relationship found in this applet could possibly exist among any other shapes or figures. This applet builds on prior knowledge and then adds to prior knowledge through challenges presented involving higher-level thinking. The strengths of this applet is that it is clear, concise, and straight to the point. Some students may understand the visualization really quickly and can use the posed questions to explore further investigations, whereas other students can explore the Pythagorean Theorem through proof form rather than symbolic representation. This builds on students' ability to analyze different relationships presented through the subject of geometry and also helps build on their understanding of the actual proof for the Pythagorean relationship. The weaknesses of this applet are that it does not provide a whole lot of guidance. There is no real way for the students to assess themselves based on this applet to see if they are doing the activity right. Depending on what type of activity they are working on, open or close-ended, this could pose as a strength or a weakness. I think that another strength to this activity is that there are extensions at the end that the students can build upon through the use of this particular applet. I believe that this applet could provide more of a student type assessment through the website in order for students to explore their thoughts and then get feedback on their work. However, this can also be a strength based on how the applet is being used. The actual activity in this inquiry based applet could pose as a good assessment method for the teacher rather than self-assessment for the student.
