Key facts behind this multiply test
- Partial products are the answers to each smaller multiplication; add them for the final product.
- Distributive property: 6 × 47 = 6 × 40 + 6 × 7.
- A 2-digit by 2-digit problem has four partial products in an area model.
- For multiples of 10, multiply the basic facts and attach all the zeros: 30 × 40 = 1,200.
- Estimate first by rounding to check that the product makes sense.
How to use this multiply test
Time yourself: the test is designed for an average student in 45 minutes. Answer the questions you are sure of first, then come back to the longer ones and check your units.
