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...

How do you write a number in scientific notation? The handout and video provide an explanation on how to convert from standard form into scientific notation and vice versa. The resource also contains a short discussion about choosing...

Using numbers with varying units (money, length, volume, distance, weight), scholars put each set in order from least to greatest. There are five numbers in each set, and they are all whole numbers with units attached (numbers in each...

Your second graders explore two digit addition with regrouping. They will investigate problem solving strategies within the context of a trip to the zoo. Multiple resources and assessments are provided.

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...

Expand addition concepts by challenging your pupils with these multi-digit addends. They add up numbers with up to seven digits, regrouping where needed. The first six are written vertically and the next two are horizontal. Make...

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...

Learners solve math problems involving subtracting with regrouping. They practice the steps for subtracting in the hundreds place with regrouping, through teacher guided practice. Independently, pupils complete story problems involving...

In this rounding four-digit numbers worksheet, students read the multi-step story problem, complete the table and write an explanation of their answer.

In this column addition instructional activity, students add four-digit numbers together with decimals that represent money. They then turn the horizontal problems into vertical problems and complete 20 of them.

How many hundreds, tens, and ones are there? The class examines 3 different images, each containing flats, rods, and units. They write down the number of 100s, 10s, and 1s, then the whole number they represent.

Explore two-digit multiplication with your class as they work in groups to build models of two-digit multiplication using base 10 manipulatives. They construct rectangles replacing standard numbers with equivalent place values using...

A short video introduces place value in addition and subtraction. As a class, your students identify all even numbers up to one hundred and explain the pattern. They use addition strategies to fill in the missing numbers on the number grid.

Second graders count the number of balloons represented in groups of hundreds, tens, and ones, then compose a three-digit number. There are three problems to solve.

Practice comparing number values in a variety of activities on this worksheet. Youngsters complete a statement comparing 20 to 20, choosing from three options: is greater than, is less than, and is equal to. Then, they put four numbers...

Comparing number value is an important skill and can become more complicated once scholars are dealing with three-digit numbers. For 10 pairs of numbers, scholars fill in a box between them with the greater than, less than, or equal to...

Boiling down any division problem to a one-digit divisor problem sure makes estimation easy. The lesson shows how to estimate division problems by using place value understanding and basic arithmetic facts to simplify the division. Some...

Learners participate in hands-on activities using a hundreds chart and counting toes and fingers. They discover the patterns that are created when counting by ten. After a lecture/demo, students practice by using a worksheet embedded in...

Youngsters explore number patterns within a Hundreds Chart. They discover six specific patterns from six teacher-directed rules in cooperative groups and describe in words ONE of the three patterns in their Learning Logs. They prove for...

Get your little mathematicians moving with this experiential activity in which one child is the "tens" and another is the "ones." They collect the number of unifix cubes (in tens or singles) assigned to their respective place values and...

How well do your 2nd graders know their place values? Build number sense and prime your class for the rigors of multiple-digit math with this Jeopardy game. They will need to identify numbers in the ones, tens, and write double-digit...

Here's a worksheet that provides opportunities to dissect 2-digit numbers into tens and ones. Given 6 numbers, learners write the 10s digit in a box and the digit in the ones place in another. With large type and sizable boxes, this tool...
