The worksheet titled "Two-Digit by One-Digit Multiplication Practice" gives students practice multiplying a double-digit number by a single-digit number. A grid of boxes surrounds the numbers and keeps them aligned, with three empty boxes at the bottom where students write their answers. Single-digit factors range from 2-9 and skip 1 and 0 for students who have already mastered that concept. Double-digit factors range from 11 to 99, with 0 making an appearance in the ones digit in some problems. Each worksheet page features 25 problems.

After students have begun to master single-digit multiplication, it's time to introduce double-digit multiplication. Start with one double-digit factor and one single-digit factor as they learn. It can be especially helpful to place the numbers in the problem inside a grid of boxes to keep everything aligned. That way, students can see which numbers to multiply and exactly where to put their answer.

Students can complete worksheets on their own, you can practice solving problems together as a class, or they can work through problems together in pairs. You can keep things interesting by asking one partner to solve the ones multiplication problem and the other partner to solve the tens multiplication problem then add their answers together. Once students have gotten plenty of practice, you can try timing them to see how fast they can find the correct answers.
