In this topic, students will:
use unit squares to find the area of a shape
use unit squares to find the area of a figure
use standards units to measure the area of a shape
use unit squares and multiplication to find the areas of squares and rectangles
use areas of rectangles to model the Distributive Property of Multiplication
use areas of rectangles to find the area of irregular shapes
Vocabulary:
Area - the number of unit squares needed to cover a region.
Unit square -Â a square with sides 1 unit long, used to measure the area
Square unit - a unit square has 1 square unit of area
Estimate - to give an approximate number or answer
At-home Practice:
Supplies:
a deck of cards (Remove face cards)
graph paper
2 different types of writing utensils (Give one to each player)
Split the deck evenly between players. Player 1 flips over 2 cards and draws a rectangle using the cards as side lengths. Then he/she calculates the area of the figure. (Ex. Player 1 flips over a 3 and 5. Player 1 draws a rectangle that is 3 squares long by 5 squares wide. He/she calculates the area to be 15.) Player 2 then goes. Continue playing until the graph paper is full.
