Adding Tens Quizzes

Use base-ten blocks, place-value charts, or an open number line to show that adding a multiple of ten changes the tens place while preserving the ones place unless regrouping is required. Connect each model to mental strategies such as counting forward by tens and decomposing larger addends.

Begin with adding 10 to two-digit numbers, then introduce 20, 30, and larger multiples of ten across varied number ranges. Include missing-addend problems, number patterns, open number lines, and short mental-math sprints to build flexible place-value reasoning rather than rote counting.

Students may change the ones digit, count by ones instead of tens, or overlook regrouping when a sum crosses into a new hundred. Have them identify the tens and ones before calculating and verify that the ones digit remains unchanged in problems that do not require regrouping.

Wayground quizzes are available as printable PDFs and digital formats, so teachers can run an adding tens quiz as a digital quiz or print it for centers, homework, fluency practice, or assessment. Every quiz includes a complete answer key, and paper submissions can be scanned or captured for grading with the Wayground for Teachers app.

Common Core develops adding tens through place-value understanding, mental addition, and strategies based on composing and decomposing numbers. This work prepares students for fluent multi-digit addition and for explaining why standard addition algorithms work.

Adjust the number range and quantity of problems, using visual place-value supports for developing learners and larger numbers or missing-value tasks for enrichment. Wayground also supports extended time, Read Aloud, reduced answer choices, and reading mode, while alternate quiz versions can use larger text, wider spacing, a dyslexia-friendly font, or translation.
