This Grade 3 medium sheet 3 has students apply commutative and associative properties to multiply more efficiently. Grade 3 learners rearrange factors like 4 x 3 x 25 and group friendly pairs such as 5 and 2 to form tens or hundreds. Nine fill problems plus a matching activity compare rearranged expressions with their products, building Grade 3 number sense and flexible thinking with multiplication facts and strategies.

Properties of Multiplication
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Grade 3 commutative: 4 x 7 = 7 x 4 so the product stays the same.
2. Grade 3: use commutative to rewrite 2 x 9 as 9 x 2 and solve to 18.
3. Grade 3 associative: (2 x 3) x 5 = 2 x (3 x 5) = 30.
4. Grade 3: to solve 5 x 7 x 2 easily, first do 5 x 2 = 10, then 10 x 7 = 70.
5. Grade 3: 4 x 3 x 25 = 4 x 25 x 3 = 100 x 3 = 300.
6. Grade 3: 6 x 5 x 2 = 6 x (5 x 2) = 6 x 10 = 60.
7. Grade 3 commutative: 8 x 3 = 3 x 8 with product 24.
8. Grade 3: (4 x 2) x 6 = 4 x (2 x 6) = 4 x 12 = 48.
9. Grade 3: 7 x 2 x 5 rearranges to 7 x (2 x 5) = 7 x 10 = 70.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
