Third Grade Geometry

Geometry for many can be extremely difficult and quite boring. My goal with this blog post is to explore an activity that could be made interactive as to get a majority of students involved and really help those kinesthetic learners. As I was looking activity sheets found the following that once modified would be great for third grade geometry.

I thought this activity sheet was a good starting point but could easily be very easy depending on the student. A way to make this more interactive for students is to have students cut out each box and mix and match to make the largest area using a maximum of four shapes.

Standards

3.MD. 6. Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).

3.MD. 7. Relate area to the operations of multiplication and addition.

• Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths.
• Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving real world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning.
• Use tiling to show in a concrete case that the area of a rectangle with whole-number side lengths a and b + c is the sum of a × b and a × c. Use area models to represent the distributive property in mathematical reasoning.
• Recognize area as additive. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real world problems.
