-40 task cards (calculating the perimeter and area of rectangles)
-Cards are numbered from 1 to 40
-Each card has an answer on top
-Below the answer is a question
-No matter which card a student starts on, if they solve the
question correctly, they will follow in the the same order
EXAMPLE: If I start on card #1 and my answer is 12, I will look at the TOP of all the other cards until I find 12. If card #8 has 12 on top, I will solve question 8 next. I will continue this process until I have made it back to where I started.
This is a great way for students to self-check! If they can't find their answer, they know they did something wrong!
TEKS/STAAR ALIGNED (GRADE 4):
4.5C: Use models to determine the formulas for the perimeter of a rectangle (l + w + l + w or 2l + 2w), including the special form for perimeter of a square (4s) and the area of a rectangle (l x w)
4.5D: Solve problems related to perimeter and area of rectangles where dimensions are whole numbers
COMMON CORE ALIGNED (GRADE 3):
-CCSS.MATH.CONTENT.3.MD.C.7.A: 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.
-CCSS.MATH.CONTENT.3.MD.C.7.B: Multiply side lengths to find areas of rectangles with whole-number side lengths
CCSS.MATH.CONTENT.3.MD.C.7.C: 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.
-CCSS.MATH.CONTENT.3.MD.D.8: Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.
