These number frames are a reimagining of the common “numicons" as all the numbers build upon 5 as a visual benchmark. This set also includes a pegboard for looking at how the numbers add together in reference to 10 (the pegboard is 10 when filled). 

They can be used for addition/subtraction and general number sense. Using the pegboard helps students with combinations for 10, but also for understanding regrouping when numbers are over 10 (i.e., seeing that 7+5 is the same as adding 7+3 and then 2 more).
