Math activity for elementary school! Hundred chart hidden pictures. Includes 20 color-by-number hidden pictures for use with a hundred chart. Includes a 100 chart with all the numbers, a blank 100 chart, and two charts with missing numbers for an extra challenge. Also includes a full-color answer key. Great for learning number sense. I use these for kindergarten, first grade, and second grade. NOW IMPROVED! LARGER FONT SIZE AND IMPROVED SPACING!
