Adding Decimals 0 2 Digits Missing Addend Practice Activities

Class 6 maths worksheets for finding missing addends in decimal addition with whole numbers, tenths and hundredths.

Practice that builds confidence

What this skill covers

These Class 6 maths worksheets help children practise missing addend problems in decimal addition, such as 4.5 + ___ = 7.25 or ___ + 2.06 = 9. Children learn to reason from the total and the known addend instead of simply adding left to right.

The printable activities include decimal addition equations with 0, 1 or 2 decimal places, space to align place values, and varied formats that build fluency with tenths, hundredths, zero placeholders and checking by addition.

In the Decimals Addition Subtraction strand, missing addend work connects addition and subtraction. A child sees an equation like 6.30 + ___ = 8.75 and understands that the unknown part can be found by subtracting the known addend from the total. The focus is on decimals with 0–2 decimal digits, so learners work with whole numbers, tenths and hundredths while keeping the decimal point fixed.

Progression in the worksheets

The practice moves from friendlier equations where the missing number is easy to see, to examples that require regrouping across tenths or hundredths. Children may meet totals written as whole numbers, such as ___ + 3.48 = 10, as well as mixed decimal lengths, such as 2.7 + ___ = 5.35. This variation helps them realise that 2.7 can be treated as 2.70 when hundredths are needed.

Parent practice routine

At home, ask your child to read the equation aloud: “known addend plus missing addend equals sum.” Then have them rewrite it as a subtraction sentence, align the decimal points, add zeros if helpful, and solve. Finish each problem by putting the answer back into the original addition equation. This quick check builds accuracy and confidence without turning the task into memorisation.

Classroom uses for teachers

Teachers can use these sheets for independent practice after modelling decimal alignment, for maths centres, or as a short review before mixed decimal addition and subtraction. They also work well for partner checking: one child solves the missing addend, and the other verifies it by addition. The format makes it easy to spot whether a learner understands inverse operations or is guessing.

Common errors to watch for

Many mistakes come from misaligned decimal points, ignoring placeholder zeros, or subtracting the smaller visible decimal from the larger-looking decimal without considering place value. For example, in 4.8 + ___ = 6.05, children may forget to write 4.80 before subtracting. Encourage neat columns and labels such as ones, tenths and hundredths.

Helpful answers

Frequently asked questions

What does “0–2 decimal digits” mean in these worksheets?

It means the numbers may be whole numbers or decimals with one or two digits after the decimal point, such as 8, 3.4 or 6.25.

How should a child find the missing addend in a decimal addition equation?

They should subtract the known addend from the total, align the decimal points carefully, add placeholder zeros if needed, and then check by adding the answer back.

Why are some numbers written with extra zeros, like 2.7 as 2.70?

Extra zeros help show the same value in hundredths. Writing 2.7 as 2.70 makes it easier to line up decimal places when subtracting or adding.

Are these worksheets suitable before decimal subtraction practice?

Yes. They are a useful bridge because children use subtraction to find an unknown addend while still checking their answer through addition.

What is the most common mistake in missing addend decimal problems?

The most common mistake is not aligning decimal points, which causes tenths and hundredths to be placed in the wrong columns.
