Here is a "fin"tastic activity to use to teach your students how to count, add, or subtract to 20! These cute fish tank ten-frames and twenty-frames (double ten-frames) mats can be used during whole group instruction, small math groups, independent practice, or placed in a math center.
This fun activity comes with one ten-frames fish tank mat, a twenty-frames fish tank mat, and ten cute red, orange, yellow, green, blue, light blue, purple, and pink fish to choose from to use as manipulatives. If you need 20 counters for your twenty-frames mat, simply print the the colored fish manipulatives page that you need twice! You can also use cute plastic fish or mini fish erasers to use as counters to use with these mats if you prefer. Have a "fin"tastic time teaching math to your students this year!
