By 3rd grade your children will likely already have been introduced to inches, feet, centimeters, and meters as units of measurement and these units of length as are now the basis of square units for measuring area. The activity worksheets below will give "hands-on" practice with using square centimeters and square inches.
Note: Some of the worksheets below required unit squares to be printed and cut out. If you have card or stiff paper then this will make manipulating these much easier.
This units of measurement worksheet involves cutting out square inch units and using them to measure the area of rectangles and this worksheet repeats the activity with square centimeters .
Use the square inches and square centimeters to measure various household shapes. Discuss with your children:
This measurement worksheet challenges students to find areas by counting square centimeters and further challenges them to draw shapes of a specific area.
As illustrated below, the number of square units in each column and each row equates to the length of the rectangle’s sides. Do not assume that your children will immediately make this connection.
This activity worksheet will help your children make the important connection between the number of units and the lengths of the sides. Discuss whether you can find the area using the number of rows and number of columns. Your children may be able to visualize the missing parts and count all the squares or they may start to see how addition or multiplication can be used.
Note: You may wish to reuse the unit squares that were printed and cut out for an earlier worksheet.
