Previously Published Data 

1.) Students will write number families using teacher-made number fact cards. They may use blocks to help them with computation. They will record the number facts on the Number Families Sheet. 

2.) Students will practice counting, reading, and writing mathematics patterns in addition and subtraction, showing the inverse relationship between addition and subtraction facts. They may use charts, flash cards, and games. 



Previously Published Data 

1.) Students will write two addition facts and two subtraction facts using number families of two- and three-digit numbers. 

2.) In their Mathematics Journals, students will record a sampling of number families to 1000 that indicates their understanding of inverse relationships of addition and subtraction facts.
