Practice that builds confidence
From blocks to counted numbers
These Class 1 counting practice activities help children count base ten blocks carefully and say how many there are in all. Children look at groups of tens and single ones, then connect the model to a number.
The printable worksheets include clear block pictures, counting prompts, and number-writing spaces. They support early place value, one-to-one counting, and confidence with tens and ones in the Mathematics > Class 1 > Base Ten Blocks > Counting path.
Base ten blocks make counting visible. A long rod represents a group of ten, while a small unit cube represents one. In these worksheets, children practise looking at a set of blocks, counting the tens first, adding the ones, and writing the total. This builds the idea that 2 tens and 4 ones make 24, not just a random collection of shapes.
How the practice progresses
The activities move from simple pictures with a few ones to mixed groups of tens and ones. Children learn to scan the model, count by tens where possible, and then count on by ones. This is an important step before comparing numbers, writing expanded forms, or adding two-digit numbers later in Class 1 maths.
Parent routine for home practice
Sit beside your child with one worksheet and ask, “How many tens do you see?” Let the child touch or point to each ten-rod while saying 10, 20, 30. Then ask, “How many ones?” and count on: 31, 32, 33. Finally, have the child write the number and read it aloud. If real objects are available, use pencils bundled in tens and loose pencils as ones to connect the picture to daily life.
Classroom uses for teachers
Teachers can use these pages during maths centres, small-group reinforcement, or quick independent practice after introducing base ten blocks. The sheets also work well for oral counting: one child identifies the tens, another counts the ones, and the group agrees on the final number. This helps teachers notice who is counting every block one by one and who is beginning to use place value efficiently.
Common errors to watch for
Some children count a ten-rod as one instead of ten. Others reverse the digits, writing 42 for 2 tens and 4 ones. A few may skip a unit block because their eyes move too quickly across the picture. Encourage children to mark each group as they count, say “tens first, ones next,” and check whether the written number matches the blocks.

Why iBloom worksheets help
iBloom worksheets keep the focus on one clear skill: counting base ten block models. The uncluttered layouts give children enough space to observe, count, and write. A child-friendly strategy is: “Circle the tens, count by ten, then tap the ones.” This simple routine turns counting into a repeatable habit.
Helpful answers
Frequently asked questions
What do children practise in these counting worksheets?
Children practise counting base ten block pictures, identifying groups of ten and single ones, and writing the total number shown by the model.
Are these worksheets suitable for Class 1 maths?
Yes. They are designed for Class 1 children who are learning early place value through tens and ones using base ten blocks.
How should my child count a ten-rod?
A ten-rod should be counted as 10, not as 1. Encourage your child to count rods by tens first, then count the single unit blocks one by one.
What if my child writes the digits in the wrong order?
Ask them to restate the model: for example, “3 tens and 5 ones.” Then show that the tens digit comes first and the ones digit comes second, making 35.
Can teachers use these for group work?
Yes. Teachers can use them in maths centres, small groups, or oral counting practice where children explain how many tens, how many ones, and the total.
Is this Class 1 counting base ten blocks worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
