Item details
Algebra begins with a missing box. This grade 1 workbook helps children see how addition and subtraction fit together by working with number bonds, fact family triangles and number sentences that have a hidden part. Twelve pages cover bonds to 10 and to 20, missing addends within 10 and 20, missing first numbers, fact families that write all four related facts, and finding the third number in a triangle.
Two extra skills round it out: making both sides of an equation equal, and deciding whether a sentence needs plus or minus. Short harvest stories ask how many were added. Every problem is unique within the pack, the triangles and bonds are drawn from the same numbers as the key, and a separate answer key shows each filled-in box.
Great for: - Teaching the relationship between addition and subtraction - Small-group lessons on number bonds and unknowns in all positions - Homework or sub plans for the fall math unit - Review for grade 2 children who still confuse related facts
