This set of task cards is developed to encompass questions for the following Common Core Standards:
Geometric measurement: understand concepts of area and relate area to multiplication and to addition.
Cards 1-8 are written for 3.MD.C.6.
CCSS.Math.Content.3.MD.C.6 – Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).
Cards 9-16 and 19 are written for 3.MD.C.7.B.
CCSS.Math.Content.3.MD.C.7.b – 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.
Cards 17, 18, and 20 are written for 3.MD.C.7.C
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. Use area models to represent the distributive property in mathematical reasoning.
Cards 21-24 are written for 3.MD.C.7.D
CCSS.Math.Content.3.MD.C.7.d – 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.
This set of cards includes tasks in which the student will find the area of composed figures and combined rectangles. This set also includes word problems in which area needs to be determined.
