Adding and Subtracting on a Hundreds Chart is a Grade 2 mathematics worksheet that gives students 10 multiple-choice problems involving addition and subtraction within 100. Students find sums such as 45 + 26 and 67 + 30, find differences such as 73 − 26 and 49 − 20, and use missing-addend equations to complete totals of 100. The worksheet helps students connect place-value reasoning with movement by tens and ones on a hundreds chart, while also checking whether they can distinguish between addition and subtraction situations. The final four items focus on finding an unknown addend, strengthening students’ understanding of number relationships that make 100. This free printable worksheet includes a complete answer key and is suitable for independent practice, review, or a quick Grade 2 skills check.

This Grade 2 worksheet contains 10 multiple-choice questions on adding and subtracting within 100. Students solve two-digit sums and differences, including problems that add or subtract multiples of 10, then find missing addends in equations that equal 100. These item types build place-value reasoning and help students recognize the relationship between addition and subtraction.
Before students begin, model how moving down or up by tens and across by ones changes a number on a hundreds chart, then connect those movements to equations such as 67 + 30 and 49 − 20. For the missing-addend items, ask students to locate the known number and count or reason forward to 100. Have students explain why their selected option represents the required sum, difference, or missing part.
Watch for students choosing a difference when an item asks for a sum, or reversing the subtraction order in problems such as 73 − 26. Students may also change the ones digit incorrectly when adding two-digit numbers, overlook the effect of adding or subtracting a multiple of 10, or select 40 instead of 37 for 63 + ___ = 100. On the missing-addend questions, check that they find the amount needed to reach 100 rather than simply repeating or subtracting the visible number incorrectly.
This worksheet is available as a printable PDF and as a digital quiz on Wayground, with a complete answer key for all 10 multiple-choice questions. You can assign the digital version through Wayground or print it for independent practice and review. Printable submissions can be graded by scanning student work with the Wayground for Teachers app.
Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font size so the two-digit equations and answer choices are easier to scan. You can also apply a dyslexia-friendly font or translate the addition, subtraction, and missing-addend directions into another language. These options modify the worksheet file while keeping its 10-question multiple-choice format.
