Practice that builds confidence
Adding with tens and ones
These Grade 1 adding practice activities help children connect addition to place value using base ten blocks. Students count tens rods and ones cubes, combine groups, and record the matching addition sentence.
The printable worksheets include visual models that make adding two-digit numbers less abstract. Children practise seeing numbers as tens and ones, checking totals, and beginning to understand when ones can be traded for a ten.
Base ten blocks give first graders a concrete picture of what addition means. A number such as 34 is not just “three” and “four”; it is 3 tens and 4 ones. When children add with blocks, they bring the tens together, bring the ones together, and then name the total. This builds a strong bridge from counting objects to written addition.
Building the skill step by step
These worksheets support a natural progression. Children first identify the value shown by tens rods and ones cubes. Then they combine two pictured amounts and write the sum. As confidence grows, they can use the model to understand that 10 ones make 1 ten, which prepares them for regrouping without rushing into a rule-only method.
A simple parent routine
At home, choose one problem and ask your child to say, “I see __ tens and __ ones.” Have them circle all the tens, count by tens, then count the ones. Next, ask them to write the addition sentence and explain how the picture proves the answer. If they get stuck, build the same problem with small objects, drawing rods for tens and dots for ones.
Classroom uses
Teachers can use these pages for guided maths groups, independent practice, centers, or quick checks after a base ten block lesson. They are also useful for partner talk: one student describes the tens and ones, while the other writes the equation. The visual format helps reveal whether a child understands place value or is only guessing from the digits.
Common errors to watch for
Some children count every cube on a tens rod as one instead of counting the rod as ten. Others add the ones but forget to include the tens, or write the digits in the wrong place. When regrouping appears, a common mistake is leaving 10 or more ones in the ones place instead of trading them for a ten.

Helpful answers
Frequently asked questions
What do children practise in these adding worksheets?
Children practise adding with base ten block pictures by counting tens rods and ones cubes, combining the parts, and writing the matching addition sentence.
Are these worksheets suitable before written two-digit addition?
Yes. The visual block models help Grade 1 students understand tens and ones before they rely on a vertical algorithm or memorized steps.
Do the worksheets include regrouping?
The activities support the idea that 10 ones can be traded for 1 ten, which is the foundation for regrouping. Children should first be comfortable identifying tens and ones.
How can I help my child if they count a tens rod as one?
Pause and review the value of each block. Ask, “Is this a ten rod or a one cube?” Then have your child count rods by tens and cubes by ones before finding the total.
How can teachers use these pages in class?
Teachers can use them for small-group instruction, math centers, independent practice, or quick checks to see whether students understand addition as combining tens and ones.
