What can you use to teach children not only numbers but also how to add, subtract, count mixed coins, understand numbers in base 10 and more? It's one of my favorite math teaching tools: a simple 100 chart!
I've used 100 chart mystery pictures to help my students learn numbers to 100 for a LONG time... since the mid 90's, but this year I've come to see more and more possibilities. Download a blank 100 chart AND a mystery picture in this FREE resource, then keep reading to learn new ways to use them!
Counting
What do you do when your students can count to 20, but can't consistently count beyond that? You count to 100 while looking at each number you say, to support their developing number sense! You can count to 100 with Jack Hartman, in more than one way, or with Finny the Shark in Super Simple Songs. Do your students prefer a hip hop beat? Try Harry Kindergarten I Can Count to 100! Give your students a blank 100 chart (like the one in the free resource listed above) and have them stand up, move their bodies, and point to the numbers along with one of these songs. This is a great time to walk around and evaluate how well each student is doing, and to help them get back on track if they're struggling.
The next logical step is to take away the music video and have students point and count to 100 without the visual and audio support. Can they do it? They know how to count to 100! Not quite? Keep practicing, they'll get there!
Recognizing and identifying the numbers
Hundreds pocket charts are awesome for a hands on learning center, and I LOVE that students can work in small groups and help each other to solve them. Pocket chart versions are also great for those students who don't like coloring, or don't have the fine motor strength to complete a whole page of coloring. It's wonderful to listen to students try to guess what the mystery picture is as they work, and if anyone puts a card in the wrong pocket its an easy fix - unlike trying to get colored pencil off the printed page on the worksheet versions!
- whole class or small group instruction focused on different features of numbers to 100. (count by 10s' or 5's, looking at decades such as all the teen numbers or all the 30's)
- Numbers represented by base 10 blocks
- Numbers represented in expanded form
- Numbers represented by mixed coins
- Numbers represented by addition, subtraction, multiplication and division
- Mixed review of lots of math skills in a bingo format,
- Why stop with numbers? Mystery pictures can be used to color by letter, or by sight word!
Let's explore some of these ideas further:
Numbers in base 10
Like so many skills, this one takes some practice to master, so why not practice in a fun way that our students will enjoy - as a mystery picture!
Have you seen a numbers in base 10 printable 100 chart? There's so little room in each square, so the only way to make one would be to have clues on multiple extra pages. If you need 4 pages per student for a printed version, and have 22 students, that's 88 sheets of paper for ONE math assignment. What if you could let every student for years use it, and only needed about 10 pages? So much better!
To make my hundreds pocket charts I've sorted my cards by the color they need to be so I can print them out on card stock, then trim them with a paper cutter. Boom! Math center I can use for years! (This set makes a cockatoo).
