Once we hit first grade and having to add three numbers instead of two can be very tricky for the students. This resource lets students practice without penalty adding three addends and finding different ways to get that sum. This can be enriched or differentiated. Students can use the 10 frame cards with pictures, they can use counters in the boxes instead of the cards, they can use just the numbers, they can go past adding to 20, and the possibilities are endless. To use, I print the Sums of cards on colored card stock and laminate. Then the small number and 10 frame cards will be printed on card stock and laminated but you will need multiple sets of these as they may use some numbers more than once. This includes sums from 0 - 20 and with a blank one to choose any number you wish. Hope your students enjoy as much as I enjoyed making this!
