These Addition Facts within 20 Missing Addends Multi-Step Algebraic Equations Task Cards help reinforce the concept of equality while deepening students' understanding of addition and subtraction. Students must first use addition to find the total on one side of the equal sign, and then use subtraction to find the missing addend within 20 on the other. This reinforces the concepts of "equal" and addition and subtraction while building fluency with facts within 20.

These Exploring Equivalence task cards are the perfect rigorous activity for your high flyers and fast finishers! Have each task card set accessible for students to work to challenge themselves to apply the operations in new ways.

Students build their algebraic thinking with equivalence by working through balance the equation activities. By integrating algebraic concepts in elementary classrooms, students develop math reasoning and computation skills while applying number sense, logic, and algebraic thinking.

WHAT'S INCLUDED:

• 2 sets of 28 task cards
• Recording sheet
• answer key

These Exploring Equivalence Task Cards are the perfect next step after working with my Addition & Subtraction within 20 Missing Addends Balance Task Cards and my Missing Addends Exploring Equivalence Task Cards. Once students understand the concept using the balance to represent the equation, they are ready to move into equations with a missing number. Once it’s introduced, these are a great extension for fast finishers, and even high ability students depending on the grade level.

I intentionally left these task cards and the recording sheet somewhat open ended. This allows you to tailor your directions to match your students’ readiness levels. You can have students just identify the missing number write an equation, and/or use a variable.

If you have not worked with equality previously, students will likely need some instruction for beginning. Once it’s introduced, these are a great extension for fast finishers, and even high ability students depending on the grade level.

These task cards are great for:

• whole class instruction
• small group instruction- both guided or independent
• fast finisher extensions
• high ability extensions
• enrichment
• reinforcement

These task cards are part of my Accessing Algebra line. Accessing Algebra is designed to focus on applying algebraic thinking with our existing standards, giving students the tools they'll need for success later. By looking at the standards in a new way, students build a deeper understanding of the standard while also building their critical and algebraic thinking.
