Taking Jumps of 10
Taking Jumps of 10:
Students who use this strategy often use a number line to demonstrate their thinking. The student will keep one number whole and then take jumps of 10 to find the answer.
Videos for Educators
Important Information:
Students often begin by counting on or counting back to the nearest decade number.
Some students add increments of tens or ones, while others add or subtract multiples of tens then ones. Students will leave one number whole and then split the other number into 10's and 1's.
This strategy uses an unmarked number line and numbers can be written in as needed.
Examples of What Students Might Do
Examples of what students might say:
"I started at 46 and took 4 jumps of 10. I then subtracted two to get my answer."
"I started at 73 and subtracted jumps of 10 until I got to 37. I then took two jumps of 3 until I have no ones left."
Strategies to Support Student Learning:
start with a 100's chart to help students see jumps being made
students can move to using an open number line
work with students on developing a strong understanding of 10
