Help build your students subtraction skills by finding the unknown! This lesson will help your students understand the relationship between addition and subtraction, as students build towers to find unknown addends.

Use this beginning of the year activity to practice counting! Students solidify an understanding of one-to-one correspondence as they compete to fill three towers. Use this EL Support Lesson alone, or alongside the lesson plan Counting Collections.

It’s time to get measuring! In this lesson students determine the lengths of different towers and then put them in order from shortest to longest.

Here comes the Ten Monster! Get ready to learn about subtracting tens in this hands-on lesson.

Build a strong foundation in place value with a fun game where students create groups of ten as they race to 100. Can be used alone or with the lesson plan Place Value Party.

Give students plenty of practice adding to 20 with this fun game! Use this scaffolded EL Lesson alone or for more addition practice before teaching the Do Math with M&Ms lesson.
