Three-Digit Minus Three-Digit Subtraction (T)

Young mathematicians solve 100 problems that require adding three-digit and two-digit numbers. Regrouping is required. The answer key is provided.

Visual models support young mathematicians as they deepen their fractional number sense in this elementary math lesson plan. Using fraction circle manipulatives, children explore basic unit fractions as they develop the fundamental...

Through a chapter from a text book, upper-elementary learners explore how to divide by two-digit divisors accurately. In the beginning, they use rounding and compatible numbers to estimate quotients when dividing two-digit divisors. The...

Hooray for word problems! This worksheet displays four containers at the top of the page for which learners must solve multiple-digit division problems. None of the dividends involved exceed the hundreds, and all of the divisors are...

Understanding the inverse relationship between addition and subtraction is essential for developing fluency in young mathematicians. Zoe and RJ explain how three numbers can form fact families that make two addition and two subtraction...

Number lines are great visual tools that can be used to teach a wide range of math topics. The final video of this series models how to use number lines when solving subtraction problems using the counting up strategy. Pause the video...

Whole numbers are the natural numbers including zero. The instructor illustrates and explains place value. She draws a place value chart and then defines each term and what the numbers mean. She writes a number in standard form and then...

This is a cute lesson that kids will be able to relate to. They are shown how to trade tens and regroup when adding and subtracting two digit numbers. The nice thing about this lesson is that it can be personalized to fit your class.

Learning how to regroup when subtracting numbers can be challenging and requires a solid understanding of place value. Walk your class through the steps with a clear and explicit presentation that addresses standard regrouping and...

The teacher gives a very thorough explanation of how to set up and multiply numbers vertically. She emphasizes place value and where the numbers go when you multiply them (carrying).
