Three digit addition can be complicated for students who do not have good number sense. The worksheets and activities in this unit focus on developing number sense while adding three-digit numbers.

Three-Digit Subtraction No-Prep Worksheets are also available.

The problems in this resource move from simple (adding 100s) to complex (regrouping at any place value) while practicing these main strategies: Use a Number Line, Use Base-10 Blocks, and Break Apart (also called Ungroup, Incremental Adding, adding by Place Value). The Break Apart Strategy is illustrated in three formats: using a V, adding 100s to 100s, 10s to 10s, and 1s to 1s, and vertically by place value. All of these strategies are the same but formatted differently for different learners. The strategies are generally repeated at each level so that students learn to apply them to different problems.

All of the problems in this resource have sums less than 1000.

Included are five levels of three-digit addition equations that move from simple to complex:
➟ Adding 100s & Tens (no regrouping)
➟ No Regrouping
➟ Regrouping
A: Regrouping 1s only
B: Regrouping 10s only
C: Regrouping 10s OR 1s
D: Regrouping 10s AND 1s
➟ Extra Mixed Practice

You can differentiate instruction and give students just what they need to successfully add three-digit numbers.

There are five main strategies that are practiced through the activities in this product as well as pages that compare the strategies.
➟ Use a Number Line
➟ Use Base-10 Blocks

➟ Add with Vs (Tens to Tens & Ones to Ones)
➟ Vertical Adding by Place Value
➟ Compare the Strategies

Activities and strategies are repeated at each level so that students know the process and can apply it with different levels of three-digit addition equations.
