Ten Groups - Subtracting

Unit 23

This math unit begins by introducing students to basic counting and identification of geometric shapes and quantities within groups of ten, under 30 items. It then progresses to more complex subtraction concepts using visual aids like base 10 blocks. Students first handle subtraction without borrowing, learning how to visually and numerically interpret and solve subtraction with larger numbers in the thousands and hundreds. The unit then advances to scenarios involving borrowing, initially omitting it, and later integrating borrowing techniques as the problems increase in complexity. The lessons transition from simple integer subtraction with visual comparisons among smaller groups to more challenging subtraction equations that include both borrowing and larger numerical values in hundreds and tens. Key skills developed throughout the unit include mathematical reasoning, visual interpretation of numerical data, understanding place values, and mastering the mechanics of subtraction within the base ten system across varying levels of difficulty.more
