Eryss play the tri-factora board game to learn about fact families

Math

• Eryss learned how to recognize fact families and understand the relationship between addition and subtraction.
• She practiced identifying the missing number in fact families.
• Eryss improved her mental math skills by quickly calculating the related addition and subtraction problems.
• She gained a solid understanding of the commutative property of addition and how it relates to fact families.

Continued development can be fostered by encouraging Eryss to create her own fact family puzzles. She can use index cards to write down numbers and challenge her friends or family members to solve the fact families. Another idea is to have Eryss create a fact family scavenger hunt, where she hides fact family cards around the house and her siblings have to find them and solve the equations.
