Properties of Operations

“Can your child use tricks like breaking up a number — working out '6 × 14' as '6 × 10 + 6 × 4 = 60 + 24 = 84' — to make multiplication easier?”

0 / 3 mastered

• ⬜Use commutativity: if 6 × 4 = 24 then 4 × 6 = 24
• ⬜Use the distributive property: 8 × 7 = 8 × 5 + 8 × 2 = 40 + 16 = 56
• ⬜Use associativity to multiply three numbers: 2 × 3 × 5 = 6 × 5 = 30
