This chart is great for teaching numbers to 100, showing odd and even numbers, explaining number patterns, teaching beginning addition and subtraction, and so much more. It includes a chart and 144 double-sided tiles (although there’s only space for 100 tiles at a time on the chart). The Pocket Chart is made from sturdy nylon and can fold out to be free-standing. It measures 19” x 19” and has ten rows of clear plastic pockets to hold the number tiles. The tiles are made from laminated cardboard and measure 1.75” x 1.75”. Numbers 1-100 are included in bold black writing. Then there are color-coded extras for multitudes of 2, 3, 5, and 10; multitudes of 2 and 3 are shown in blue, multitudes of 5 are shown in red, and multitudes of 10 are shown in green. There are also operation tiles like + and =, as well as a few blank tiles that can be used to create more numbers or symbols. Directions for a few simple activities to do with the chart are explained in the included activity guide sheet. ~Rachel
