Solve the addition exercise,
using jumps on the the number line below:
To solve the addition problem , we'll use jumps on a number line:
This method effectively demonstrates that equals 71 by reaching the end point after all the incremental jumps on the number line.
Therefore, the solution to the problem is .
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
Breaking into tens and ones makes counting easier! Jumping by 10s is faster than smaller jumps, and the remaining ones are simple to add. You could use other combinations, but this is most efficient.
Mark each landing spot as you go! Start at 15, write down 25, 35, 45, 55, 65 after each jump of 10, then add 6 to get 71. Writing helps you stay organized.
Addition always means moving forward (right) on the number line! Jumping backwards would be subtraction. Remember: addition = right, subtraction = left.
Yes! Once you understand the concept, you can add mentally: , then . The number line helps you visualize this process.
The same strategy works! Break the larger addend into hundreds, tens, and ones. For example: 234 + 567 becomes jumps of +500, +60, +7 from 234.
Check by counting your total jumps: did they equal the second number? Also verify: using standard addition as a double-check!
