Jump Strategy
About This Worksheet
Jump Strategy is a second grade mental-addition activity that helps students add two-digit numbers by making separate jumps for tens and ones. Each problem starts with the first addend and shows how the second number can be split into a tens jump followed by an ones jump. Students write the number they land on after each step and then record the final sum. For example, 36 + 18 becomes 36 + 10, followed by +8. This helps children use place value to break a larger addition problem into smaller, easier moves.
Curriculum and Grade Alignment
This worksheet is made for second grade learners who are developing flexible mental strategies for addition with regrouping. The main goal is to help students decompose the second addend into tens and ones and add those parts in sequence. Before using this page, your child should be comfortable adding 10 or 20 to a two-digit number and then adding a smaller ones amount. The next step is making these jumps mentally without written prompts. This activity supports number-line thinking, decomposition, mental math, and regrouping.
Student Tasks
On this worksheet, students will solve eight two-digit addition problems. Each problem already shows the tens jump and the ones jump, such as +10 and +8 or +20 and +4. Students write the intermediate number after the tens jump, then the next number after the ones jump, and finally the sum. Problems include 36 + 18, 47 + 15, 58 + 16, 29 + 17, 65 + 18, 38 + 24, 56 + 27, and 49 + 15. This builds addition fluency and mental place-value reasoning.
Common Challenges and Misconceptions
Some students may add the second addend all at once and skip the intended strategy. Others may treat +20 as +2 or forget which number they reached after the first jump. A child may also make the tens jump correctly but lose track during the ones step. Encourage your child to say each move aloud, such as, “36 plus 10 is 46; 46 plus 8 is 54.” This makes the sequence easier to follow.
Implementation Guidance
Teachers can use this worksheet after modeling addition on an open number line. It works well for students who understand regrouping conceptually but need a more efficient strategy than drawing base-ten blocks. Parents can draw a quick number line and show one larger jump for the tens and one smaller jump for the ones. As your child becomes more confident, encourage them to picture the jumps mentally. This helps the strategy become faster and more flexible over time.
Details and Features
This worksheet includes eight two-digit addition problems arranged in a two-column grid. Each problem provides the tens jump and ones jump directly in the equation. Students have spaces for both intermediate values and the final sum. The consistent layout keeps the mental strategy easy to follow across all eight problems. The printable supports decomposition, open-number-line reasoning, mental addition, and regrouping.
