Students get to practice their addition, subtraction, and multiplication skills on this worksheet titled "Timed Addition, Subtraction, and Multiplication Problems With Digits up to 18." Each math problem contains 2 numbers that must be added, subtracted, or multiplied, with numbers ranging from 1 to 18. Students write their starting time at the top and their finishing time at the bottom to see how long it takes them to complete all 42 math problems.

Worksheets also give students practice with deductive reasoning by asking them to make their own equations. Some give one number in the equation, while some allow students to write all three numbers in the equation. Each one contains a plus, minus, or multiplication sign in addition to an equal sign, so they create a variety of different math problems.

Once students have learned the foundation of addition, subtraction, and multiplication, it's time for them to become fluent. Inviting students to keep track of how long it takes them to complete basic math problems encourages them to find ways to add, subtract, and multiply without using one-to-one correspondence. For example, when faced with a math problem like 8 + 9, instead of starting at 8 and counting out 9 one at a time on their fingers, they might round 9 to 10 to get an answer of 18. Then they can subtract 1 to make 17, which means they find the answer much more quickly.

Asking students to create their own addition, subtraction, and multiplication equations also helps them accomplish this goal. By figuring out which numbers to put where students exercise deductive reasoning. This helps students think critically about other ways to solve math problems, encouraging them to find new ways to complete them more quickly.
