FAQs

What does this adding and subtracting decimals worksheet cover?

This Grade 5 worksheet uses 12 multiple-choice questions to practise adding and subtracting decimals, evaluating equivalent differences, and solving money and measurement word problems. It also checks rounding decimals and whole numbers to places such as the nearest tenth, whole number, or hundred, so students must apply place value as well as calculate accurately.

How can I use this worksheet to teach adding and subtracting decimals?

First model lining up decimal points and use estimation to predict whether a sum or difference is reasonable. Then have students solve the worksheet’s computation and real-world items, such as the jump-distance and piggy-bank problems, and explain how they selected each answer. Use the rounding questions to connect the size of a digit to its place value and have students justify why a number rounds up or down.

What mistakes should I watch for when students complete this decimal worksheet?

Students may misalign decimal points, subtract the smaller quantity from the larger without considering the situation, or choose a distractor based on an arithmetic error. Watch for confusion between adding and subtracting when checking an expression, especially in the item that verifies a difference through addition. In the rounding questions, students may look at the wrong neighboring digit or round to the wrong place.

How do I assign and grade this adding and subtracting decimals worksheet?

On Wayground, this worksheet is available as a printable PDF and as a digital quiz, with a complete answer key for all 12 multiple-choice questions. You can assign the digital version for online completion or print the decimal computation, word-problem, and rounding items for paper practice. Printable submissions can be graded by scanning student work with the Wayground for Teachers app.

How can I differentiate this decimal worksheet for my students?

Use the worksheet’s Advanced Settings to change font spacing or select a larger font size so the decimal expressions, answer choices, and rounding items are easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language when that better supports access to the multiple-choice directions and word problems.
