Adding Decimals 2 Digit Missing Addend Practice Activities
Printable Grade 5 decimal addition worksheets where students find the missing addend in equations using hundredths and place value reasoning.
Practice that builds confidence
From addition facts to unknown addends
These Grade 5 worksheets help children find the missing addend in decimal addition equations with two decimal places. Instead of only adding left to right, students reason from the total back to the unknown part, strengthening place value and decimal subtraction.
The printable activities include balanced equations, vertical and horizontal layouts, and problems where the blank appears before or after the plus sign. Children practise lining up decimal points, using hundredths, and checking that both addends make the given sum.
Missing addend work asks students to complete equations such as 3.45 + ___ = 7.80 or ___ + 1.26 = 4.00. The key idea is that the total is known, so the unknown part can be found by subtracting the given addend from the sum. This connects decimal addition and subtraction instead of treating them as separate skills.
Place value progression
The practice focuses on decimals written to hundredths, so students must think in ones, tenths, and hundredths. Early problems may have straightforward regrouping, while later items encourage careful trading across the decimal point. Students should read 2.36 as 2 ones, 3 tenths, and 6 hundredths, not as 236 with a dot inserted.
A practical parent routine
At home, ask your child to circle the total first, underline the known addend, and write the subtraction sentence that finds the blank. Then have them solve on grid paper or lined paper, keeping decimal points in one column. Finish with a quick check: add the answer back to the given addend and see whether it equals the original sum.
Classroom uses
Teachers can use these printables for independent practice after modeling missing addend equations, partner checking during math centers, or a short review before decimal word problems. They also work well as an exit ticket: one horizontal equation, one vertical equation, and one item where the blank comes first.
Common errors to watch for
Students may subtract the smaller number from the larger without identifying the total, misalign decimal points, forget placeholder zeros, or treat hundredths as whole numbers. If a child answers 5.4 instead of 5.40, discuss why the value is the same but the hundredths place may help with checking.

A child-friendly strategy is: find the total, subtract the known part, line up the dots, then add back to check.
Helpful answers
Frequently asked questions
What does missing addend mean in decimal addition?
A missing addend is the unknown number in an addition equation. In 2.35 + ___ = 6.10, students find the blank by subtracting 2.35 from 6.10.
Are these worksheets for decimals to the hundredths place?
Yes. The practice is built around decimal numbers with two decimal places, helping Grade 5 students work with tenths and hundredths accurately.
Should my child add or subtract to solve these problems?
Students usually subtract the known addend from the total to find the missing addend, then add the answer back to check the equation.
What is the most common mistake in this skill?
The most common mistake is not lining up decimal points. Students should write ones under ones, tenths under tenths, and hundredths under hundredths before calculating.
How can teachers use these in a Grade 5 classroom?
Teachers can use them for decimal review, math centers, independent practice, partner correction, or quick exit tickets after teaching inverse operations with decimals.
