Adding Tens Worksheets for 1st Grade

What your child practices

This set of 50 worksheets on Adding Tens is written for 1st grade (Grade 1 in Canada) and gives your child 1050 questions to work through, one page at a time. In the early grades, number sense grows through lots of short, hands on practice, and Adding Tens is one of the building blocks teachers return to all year. Each of the 50 versions of Adding Tens has new questions, so your child can repeat the skill without memorizing answers. Each sheet supports Common Core 1.NBT.C.4, covering place value and using it to add, subtract, multiply and divide. In Canada it matches the BC curriculum for Grade 2. Every PDF prints on US letter paper, with the answer key on page 2 for quick checking. New to the idea? Watch the Adding Tens video lesson, then print a sheet while it is fresh.

Tips for parents

• Keep counters, blocks or fingers nearby. Young children learn numbers best when they can touch them.
• Turn one problem into a real life question, using snacks, coins or toys around the house.
• Ask your child to explain one answer out loud. Talking through Adding Tens shows you where the thinking is solid.
