This resource helps support CCSS 1.OA.3, 1.OA.6, and 2.OA.2. Having said that, I wouldn’t limit its use to 1st and 2nd grade. My 3rd graders (and even some 4th graders!) continue to need practice with this skill.
Find the Fact Family includes two sets of number cards of 30 cards each (a total of 60 cards!) Each card has four numbers on it, 3 of which make a fact family. Students are to identify which three numbers make the fact family, and the four related facts (two addition and two subtraction.) Set One includes facts to 20. Set Two is differentiated to include facts from 30-100. Or, rather, number families from 30-100 – I realize we tend to think of ‘facts’ as only 0-20. Either way, Set Two is used exactly the same way as Set One. It just has larger numbers!
What I like about these cards is their versatility. You could use them as a whole group activity: hold the card up, wait for volunteers to identify the fact family. This is a great math warm up, or a transitional activity no matter what time of day. Find the Fact Family also makes a great math center. Students take a card, identify the facts, and then show their thinking. I’ve provided two different recording sheets for the math center. One is a full-page, and has kids write the numbers on their card, make a picture representation of the fact family, and then write the related facts. Great for those kids who haven’t yet moved to abstract knowledge with this concept. The second recording sheet is a half page, and once kids have identified the related facts, then they need to show their strategy/prove their answer is correct. Finally, I’ve also included a ‘Fact Family Frenzy’ game board for use with two players. Directions are on the board.
Thanks for checking it out!
