This resource is designed to help students build number sense and mental math fluency. Each page consists of a series of “number crosses,” where students start with a central number and must determine the values that are:
10 less (the number above)
10 more (the number below)
1 less (the number to the left)
1 more (the number to the right)
This repetitive practice is excellent for developing a strong understanding of place value and improving quick mental calculation skills for two-digit numbers.
