In this activity students use pictures to add or subtract and then match the equation to the correct answer in a memory/concentration type of game. For example, students count the bugs (5) - (3) bugs and have to match it to the card with the number 2. Print on card stock and laminate for durability. Great for a math center activity, a finished work activity, a teacher guided or parent volunteer activity. You can write the answers on the back of the equation so the activity can be self checking. This file also contains 2 worksheets similar to the activity for additional practice or assessment. This activity can be used for Kindergarten students or lower level first graders.
