Bridge to Ten
About This Worksheet
Bridge to Ten is a second grade mental-math activity that teaches students to break apart an addend so they can first reach the next multiple of 10. Instead of adding all of the second number at once, children split it into two smaller parts. One part completes the first number to the next ten, and the remaining part is added afterward. For example, the model shows 28 + 7 as 28 + 2 = 30 and then 30 + 5 = 35. This strategy helps students use friendly tens to make regrouping easier to understand and calculate mentally.
Curriculum and Grade Alignment
This worksheet is intended for second grade learners who are developing flexible strategies for addition with regrouping. The main goal is to help students decompose a one-digit addend in a useful way so the first addition step lands on a multiple of 10. Before beginning, your child should know the complements needed to reach the next ten, such as knowing that 36 needs 4 to reach 40. The next step is using make-a-ten reasoning mentally without needing every intermediate blank. This activity supports number sense, decomposition, and efficient mental addition.
Student Tasks
On this worksheet, students will solve eight addition problems using a break-apart strategy. For each one, they split the second addend into the amount needed to reach the next ten and the amount left over. They first add enough to make the friendly ten, then add the remaining part to find the final sum. Problems include 36 + 8, 47 + 6, 58 + 7, 29 + 5, 65 + 8, 78 + 5, 39 + 6, and 54 + 9. The provided blanks guide students through both decomposition and calculation.
Common Challenges and Misconceptions
Some students may split the second addend randomly instead of choosing the amount that reaches the next ten. Others may use the correct first part but forget that the two broken-apart pieces must still equal the original addend. A child may also stop after reaching the friendly ten and forget to add the remainder. Encourage your child to check the split first, such as confirming that 8 = 4 + 4 before solving 36 + 8. This keeps the decomposition accurate.
Implementation Guidance
Teachers can introduce this worksheet after reviewing partners that make 10 and multiples of 10. It works well with an open number line, where students can visibly jump to the next ten and then make the remaining jump. Parents can ask, “How many does 36 need to become 40?” before discussing the rest of the addend. Once the child becomes comfortable, encourage them to explain the strategy without writing every step. This helps the method grow into useful mental math.
Details and Features
This worksheet includes a worked example followed by eight guided make-a-ten addition problems. Each problem provides blanks for breaking apart the second addend, reaching the next ten, and adding the leftover amount. The orange-bordered layout keeps the steps organized and easy to follow. Every equation is chosen so bridging through a multiple of 10 is useful. The printable supports decomposition, mental math, friendly-number strategies, and addition with regrouping.
