Adding Decimals 1 Digit Plus 2 Digit Practice Activities
Class 4 maths worksheets for adding decimals with tenths and hundredths, using place value, decimal alignment and careful regrouping.
Practice that builds confidence
What this skill covers
These Class 4 maths worksheets help children practise adding a decimal with 1 digit after the point to a decimal with 2 digits after the point. Learners build confidence with tenths, hundredths, place value and writing numbers in neat columns.
The printable activities include focused sums, mixed decimal additions and space for working. Children learn to line up decimal points, use a zero as a placeholder when needed, and check whether their answer makes sense.
Adding decimals with 1 digit plus 2 digits means combining numbers such as 2.4 + 1.35 or 0.7 + 0.28. Children see that 2.4 is the same as 2.40, so tenths and hundredths can be added correctly. This collection stays focused on that exact step: one addend written to tenths and the other written to hundredths.
Building from place value
The practice moves children from understanding decimal places to using a reliable written method. They identify ones, tenths and hundredths, align the decimal points, add digits in each column, and keep the decimal point in the answer directly below the others. Some sums may not need regrouping, while others encourage careful carrying from hundredths to tenths or tenths to ones.
A simple parent routine
At home, ask your child to read each number aloud before solving: “three and five tenths” or “one and twenty-six hundredths”. Then have them rewrite the sum vertically, adding a zero where helpful, for example 3.5 as 3.50. After solving, ask, “Should the answer be a little more than 3.5?” This quick estimation habit helps catch misplaced decimal points.
Classroom uses for teachers
Teachers can use these worksheets for classwork after introducing decimal place value, as maths centre tasks, or as revision before mixed decimal operations. They also work well for small-group support: one group can practise alignment with grid paper while another solves independently and explains the steps using vocabulary such as tenths, hundredths, sum and placeholder.
Common errors to watch for
Many children line up the last digit instead of the decimal point, turning 4.6 + 2.35 into a wrong column arrangement. Others forget that 4.6 can be written as 4.60, or they place the decimal point at the end of the answer. Encourage children to slow down, mark the decimal points first, and check that every column has the correct place value.

Why iBloom worksheets help

Helpful answers
Frequently asked questions
What does 1 digit plus 2 digit mean in these decimal worksheets?
It means one number has 1 digit after the decimal point, such as 3.4, and the other has 2 digits after the decimal point, such as 1.25.
Why should children write 3.4 as 3.40 before adding?
Writing 3.4 as 3.40 shows the hundredths place clearly. The value stays the same, but the columns become easier to add accurately.
What is the most important rule for adding these decimals?
Children should line up the decimal points, not the last digits. This keeps ones, tenths and hundredths in the correct columns.
Are these worksheets suitable for Class 4 revision?
Yes. They are useful after children have learnt decimal place value and need focused practice adding tenths with hundredths.
How can I help my child check a decimal addition answer?
Ask them to estimate first. For example, 2.6 + 1.24 should be a little less than 4, so an answer like 38.4 clearly has a decimal-point error.
