Print on of these mats for each of your students as you learn the concept of addition while using concrete materials. Place each mat into a plastic sheet protector and allow students to manipulate objects on top of the mat. Ask students to place a certain number of objects in each of the addend places. Have students record the addends on the lines provided at the bottom of the mat (using a dry erase marker), then have students move all of the objects into the final box to determine and record the sum.
This activity is a great way to check for understanding as you introduce addition.
