Task cards are a great option for early finishers, math centers, math workstations, exit tickets, morning work, small group practice, and whole group practice.
These task cards will help students practice using the "break apart" or "place value" strategy to solving addition problems involving a 2-digit number and a teen number.
The break apart or place value strategy gives students practice breaking apart a number into tens and ones allowing them to apply their understanding of place value.

- Ideas for Use
Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.
