Adding and Subtracting 10s Quizzes

Use a place-value chart or hundred chart to show that adding 10 increases the tens value while subtracting 10 decreases it. Have students compare each number before and after the operation, explain what changed, and verify that the ones digit usually remains unchanged.

Use hundred-chart moves, place-value models, number patterns, missing-number equations, and mixed mental-math problems involving 10 or multiples of ten. Include real-world contexts such as gaining or spending groups of ten so students connect the place-value pattern to meaningful quantities.

Students may change the ones digit, treat 10 as 1, reverse the operation, or overlook regrouping when a problem crosses a place-value boundary. Ask students to identify the tens and ones before solving and then estimate whether the answer should be greater or less than the starting number.

Wayground quizzes are available as printable PDFs and in digital formats, so a teacher can host the quiz as a digital quiz or print and assign it on paper; every quiz includes a complete answer key. Completed paper quizzes can be scanned or captured for grading with the Wayground for Teachers app, and printable practice gives schools a rigorous off-screen option.

This skill aligns with the Common Core emphasis on place-value reasoning and using properties of operations to add and subtract mentally. Recognizing how groups of ten change prepares students for fluent multi-digit addition and subtraction, including later work with regrouping.

Use hundred charts and two-digit numbers for students building place-value understanding, then extend practice to larger numbers, multiples of ten, missing values, or problems that cross place-value boundaries. Wayground also supports extended time, Read Aloud, reduced answer choices, and reading mode, while alternate quiz versions can adjust spacing, font size, dyslexia-friendly text, or language.
