In the Addition and Subtraction Links Worksheet Set, students fill in empty boxes to solve addition and subtraction number sentences to 20. Solving each number sentence provides a "link" to other number sentences, and helps students figure out the remaining missing numbers in each number sentence.
The worksheet set can be used in a multitude of ways. It can be used as morning work, as math center work, as an assessment of addition and subtraction with numbers to 20, as an enrichment activity, or as homework.
The worksheet set includes five addition and subtraction "link" puzzles that incorporate both addition and subtraction to 20. For some number sentences, students must find the missing addend, minuend, or subtrahend, while others require students to find the sum or difference.
The worksheet set aligns with the Common Core State Standards for Mathematics, specifically:
•CCSS.Math.Content.1.OA.B.4 Understand subtraction as an unknown-addend problem.
