Included are number bonds within 20. In one version, students determine both parts that make that particular whole. In another version, students find only one missing part. I also included two blank number bond pages.
Students are asking to determine parts that make the same whole. Students write one addition equation and one related subtraction equation. One option has traditional number sentences (___+___=___ and ___-____=___). and one option has mixed number sentences (___+___=___ and ___=____+___ or ___=____-___).).
