Hundreds Chart Worksheets to Practice Number Sense of 1 More, 1 Less, 10 More, 10 Less
This is 14 pages of practice for identifying 1 more, 1 less, 10 more and 10 less than a given number. Each page includes a 100 chart and numbers between 1-100 that your children can practice their number sense.
When I use this in my classroom, I have the students color the number in question yellow in the hundreds chart. I then have them color the number before it, and the number after it. We then discuss what is 10 less than the number (the one above it) and 10 more (the number below it. When the kids are done, if they have colored the correct numbers, their coloring should reveal a + on their hundreds chart. They can then transfer these numbers onto the answers within the page. The last page is blank so you can add your own numbers.
Fits CCSS Standards 1.NBT.1 and 1.NBT.2
