This file is for beginner algebraic thinking. It provides a balancing scale pictures with two places to subtract numbers as well as the answer in the base. Students will be required to find the missing number or numbers in various positions e.g. 9-_ = 6-3 (with 3 in the base) or 4-4 = _-2 (with 0 in the base) or 6-0 = 11-_ (with an empty base). There are 3 levels of difficult; 1 missing number, 2 missing numbers and multiple (1-3) missing numbers as well as a blank page so you can differentiate the numbers for your students needs.
