This Fact Family activity is great for students in Kindergarten, 1st, and 2nd grade. The following common core math standards are addressed:
K.OA.1 Represent addition and subtraction with objects, fingers, mental images, drawings1, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
K.OA.5 Fluently add and subtract within 5.
1.OA.3 Apply properties of operations as strategies to add and subtract.2 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
1.OA.4 Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8. Add and subtract within 20.
1.OA.6 Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.
2.OA.2 Fluently add and subtract within 20 using mental strategies.2 By end of
Grade 2, know from memory all sums of two one-digit numbers.
2.NBT.9 Explain why addition and subtraction strategies work, using place value and the properties of operations.
About the activity:
The “Haunted Fact Family House” can be used as a part of a center activity or as a whole-class activity. It makes for a great display around Halloween! Depending on the levels in your classroom, you can ask students to pick their own addends or have them roll 2 dice to get addends. In the younger grades, you may just want to give everyone +1 facts. Please make sure to tell students that they CANNOT use double facts for this activity. If they roll a double, ask them to roll again so they can make 2 different addition & 2 different subtraction sentences. After students complete their fact families, I usually trace over their writing with a Sharpie and let them decorate their houses with crayon, making them as SPOOKY as possible. For added fun, you can purchase “googly eyes” and give each student a few to glue onto their papers. Also, I usually back students’ papers with construction paper if I am going to use them as a bulletin board display.
