Practice that builds confidence
Building the idea of 8
These Grade 1 addition worksheets help children practise the number bonds that make 8: 0 and 8, 1 and 7, 2 and 6, 3 and 5, and 4 and 4, including the turn-around facts.
The printable activities use part-part-whole diagrams, missing-addend questions, matching tasks, and simple equations so children connect pictures, numbers, and addition vocabulary.
Number bonds show how one whole number can be split into two parts. On this page, the whole is always 8, so children focus on finding the missing part instead of learning a new total each time. A worksheet might show 8 as the whole with 3 in one part, asking for 5, or show the equation 6 + __ = 8.
From models to facts
The practice moves from visual support to more independent thinking. Part-part-whole circles help children see that the two parts join to make 8. Matching and fill-in activities then connect those models to addition sentences such as 2 + 6 = 8 and 6 + 2 = 8. This helps children notice the commutative property without needing formal language.
Parent routine for home practice
Choose one worksheet and keep eight small objects nearby, such as coins, buttons, or cereal pieces. Ask your child to make 8 in two groups, say the bond aloud, and then write the matching equation. Repeat with a different first part: “If one group has 7, how many more make 8?” End by asking your child to name all the bonds for 8 in order.
Classroom uses for teachers
Teachers can use these pages for morning work, addition centers, small-group reteaching, or quick checks after introducing part-part-whole models. They also work well with ten frames, counters, linking cubes, or number lines. For students who finish early, ask them to write the related turn-around fact or draw a story problem for one bond.
Common errors to watch for
Some children count both parts and the whole, making totals larger than 8. Others reverse the task and write 8 as a part instead of the whole. Watch for skipped bonds, especially 0 + 8 and 4 + 4, and for children who rely only on guessing. Encourage them to check by counting on or by combining two groups.

Why iBloom worksheets help
The worksheets keep the total fixed at 8 so children can build confidence with a small, important set of facts. Clear layouts, repeated visual structures, and varied question types help students move from counting objects to remembering combinations. A child-friendly strategy is: “Start with the part you know, count up to 8, and the counts you say are the missing part.”
Helpful answers
Frequently asked questions
What are the number bonds for 8?
The number bonds for 8 are 0 and 8, 1 and 7, 2 and 6, 3 and 5, and 4 and 4, plus the reversed addition facts such as 7 + 1 and 6 + 2.
Why practise only number bonds that make 8?
Keeping the total fixed at 8 helps Grade 1 children focus on how parts combine to make a whole. This builds fact fluency and prepares them for missing-addend problems.
How can I help my child if they guess the missing number?
Use eight counters. Show the known part, then have your child count how many more counters are needed to reach 8. After building it, ask them to write the equation.
Do these worksheets include visual models?
Yes. The activities include part-part-whole style practice and number-based questions so children can connect concrete groups, diagrams, and addition sentences.
Are number bonds to 8 useful for subtraction too?
Yes. Once children know that 3 and 5 make 8, they can also understand related subtraction facts such as 8 - 3 = 5 and 8 - 5 = 3.
