There is an empty frame for 10, and 20. You can laminate the mats, or place them in sheet protectors, and let the little astronauts use dry-erase markers. Wipe off when they are done. Or you can cut out the numbers and the pictures at the end of the file to fill up the frames. Numerals 1 through 20, along with the spelled numbers, are provided.
For other ten frames fun, or space themed math fun, please see my product listings.
Ten frames are great to understand place value, are great visual tools for helping students to not only see the numbers and count - connecting counting to cardinality, but it's great with quick mental addition and subtraction, start composing and decomposing numbers into tens and ones etc. They are aligned with the Common Core Standards!
