Here are some practice problems with adding and subtracting three-digit numbers. Scholars complete three addition problems and three subtraction problems. None of these involve carrying over or regrouping. There are only two numbers to...

Addition and subtraction are essential skills for all young mathematicians. Explain the step-by-step process with respect to place value using these real-world examples. Focus is on numbers in the tens, hundreds, and thousands, making...

There are some missing parts in these addition and subtraction problems. Scholars start by completing two number sentences, each involving all three-digit numbers. Then, they examine another number to determine the value of the tens...

Now that your class can add by 10s they can start subtracting by 10s. This clear, learner-friendly activity provides a good example (10-rods are pictured) and 7 problems to solve. Relates groups of tens to single-digit numbers, which...

Give your scholars some basic practice with addition and subtraction problems. Because the answers are explained at the bottom, consider projecting this and covering up the bottom, revealing only after class responses have been shared....

These addition and subtraction problems probably aren't written the way your scholars are used to seeing them, especially since they have double-digit addends and subtrahends. This set of eight horizontal equations gives...

Three-digit numbers are the name of the game here! Scholars convert 456 to expanded form, then complete one addition and one subtraction problem. The equations are written vertically, and the addends produce a four-digit number. There is...

Mental mathematicians add and subtract 1, 10, and 100 from sets of numbers. Each set of one, two and three-digit numbers gives scholars a chance to practice their addition and subtraction skills. There are 62 whole numbers in all. What...

Primary graders develop strategies to assist them with addition and subtraction. They discover number combinations and numerical facts which enable them to add and subtract more effectively. Students use these techniques to complete...

Students will add and subtract numbers less than 100 as well as understand and use the inverse relationship between addition and subtraction. They compose/decompose numbers up to 10 and understand a variety of situations in which...

Rate the resource as a perfect 10. Pupils use an interactive to help add and subtract numbers. They first explore how to express whole numbers using hundreds, tens, and ones, then explore how to add whole numbers by combining to make...

Students add or subtract fraction parts of mixed numbers before adding or subtracting the whole number parts. In this fractions lesson, students learn to use a ruler to help them add and subtract fractions with like denominators.

In this finding the sums and differences instructional activity, students write the equations in the ones and tens columns and solve and also solve vertical problems with and without regrouping. Students solve 18 problems.

Exercise those mental math muscles! This instructional activity contains 10 addition and 10 subtraction problems which require learners to compute sums or differences in their heads. A quick review at the top of the page provides a...

Get learners to analyze two-digit numbers based on place value, and use manipulatives to add and subtract both 1 and 10. A place value chart is available, and you can project it during guided practice. Through visualizing...

Here is an assessment designed to test mathematicians' knowledge of writing numbers, comparing numbers, skip counting, solving addition and subtraction problems; along with measuring objects, telling time, identifying shapes, reading...

In this math worksheet, young scholars solve problems involving money. The first problem has four questions that guide the student through the problem solving process. The final four problems are computation problems involving money, but...

Second graders access prior knowledge of addition and subtraction using two-digit numbers and calculate easily with them. In this three-digit addition instructional activity, 2nd graders learn to add and subtract three-digit numbers with...

For this addition worksheet, students use pictures of bars and numeric problems to add whole tens and complete addition problems. A website reference is given for additional activities. 

For this addition worksheet, students add groups of tens and their remainders to determine the missing addends in the pairs of 2-digit problems and then find the sums. Students solve nine problems.
