Getting Ready

Hundred charts are a powerful tool for teaching kids about place value because students can quickly recognize helpful patterns: Numbers increase by ONES when they read left to right across a row. Numbers increase by TENS when they jump to the row directly below their starting point!

To prep the mystery numbers sheets, I simply printed the pages on brightly colored paper so they would pop and slid them through our laminator to make them reusable.

Then, I cut along the line to separate the halves and grabbed our Vis-a-vis marker.

That’s it! We were ready to jump in and solve our number mysteries.

Solving Mystery Numbers

The set comes with 20 different sheets so my first grader, Avery, grabbed the top one and started filling in the empty circles.

She’s been practicing the numbers to 120 in school, so she was able to solve them pretty quickly, but if you have students who need a little help, give them a hundred chart to use for reference.
