This week we started exploring area and perimeter. We reviewed the formula for perimeter: s + s + s + s or 2 x length + 2 x width, and the formula for area: length x width. We really enjoyed solving open-ended word problems using manipulatives!
1) Come up with as many different designs as you can with 1 red (2 cm), 2 light green (3 cm), and 1 pink (4cm) cuisenaire rods. Find the largest and smallest perimeters.
2) Create a 6 sided figure with an area of 24 square units without using any rod shorter than a light green rod.
3) Create an 8 sided figure with an area of 28 square units, and a perimeter of 24 square units. Use no rod shorter than a light green rod or longer than a yellow rod.
4) Use exactly 8 rods (no rod shorter than a red rod or longer than a dark green rod) to create an 8 sided figure with an area of 35 square units and a perimeter of 42 units.
