Facts and Strategies Review

Ask your child to circle the sign before solving each problem. Use multiplication to check division answers and division to check multiplication answers. Use the review page as a check before moving on to multi-digit multiplication or long division.

Review factors, multiples, area models and division checks with a mix of problems. A factor multiplies to make a product. A multiple is a number times 1, 2, 3 and so on. A quotient is a division answer. The directions on the page read: Read the example. Then, solve each problem and write the answer (a number, or Yes or No) in the box. The page opens with a worked example, and the answer key shows every answer.

Yes, both. We made it for 4th Grade multiplication, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with mixed multiplication and division. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Multiplication and division undo each other, so a student can check a quotient by multiplying. Mixed sheets build this habit and keep both skills fresh.

It is a set of four facts that use the same three numbers. The numbers 6, 7 and 42 give 6 × 7 = 42, 7 × 6 = 42, 42 ÷ 6 = 7 and 42 ÷ 7 = 6.

Use it as a check before moving on to multi-digit multiplication and long division. The answer key shows each answer so you can spot which facts or strategies need more practice.

Fourth graders should multiply a whole number of up to four digits by a one-digit whole number and multiply two two-digit numbers using strategies based on place value and the properties of operations (CCSS 4.NBT.B.5). They should understand multiplication as an area model and connect partial products to the standard algorithm. Students should also multiply fractions by whole numbers and apply multiplication to solve multi-step word problems. Worksheets that progress from one-digit-by-multi-digit problems to two-digit-by-two-digit problems, using both the area model and the standard algorithm, help students build understanding alongside procedural fluency. Estimation of products using rounding should accompany exact computation to develop the habit of checking reasonableness.

Start with the area model: draw a rectangle divided into four sections representing the tens and ones of each factor. For 23 times 15, the sections show 20 times 10, 20 times 5, 3 times 10, and 3 times 5. Add the four partial products (200 plus 100 plus 30 plus 15 equals 345). Then show how the standard algorithm performs the same calculation in a more compact format. Worksheets that display the area model next to the standard algorithm for the same problem help children see that each step in the algorithm corresponds to a section of the rectangle. This connection between the visual model and the procedure builds understanding that lasts, rather than rote memorization of steps that are easily forgotten.

The area model represents multiplication as the area of a rectangle, making the distributive property visible. It shows exactly what each partial product represents and why you cannot simply multiply the ones digits and tens digits separately. This visual representation prevents the common error of multiplying 23 times 15 as 2 times 1 followed by 3 times 5. The area model also connects to real-world applications (finding the area of a room) and previews algebra (multiplying binomials). Worksheets that guide students through the area model with grid-based drawings, then transition to the open area model without grid lines, then to the standard algorithm, create a progression from visual understanding to efficient computation that many math programs now recommend.
