Use this lesson to familiarize students with the place value of each digit within a three-digit number, along with practicing the written form of three-digit numbers. Use prior to teaching Place Value Hop or as a stand alone activity.

Students will get plenty of practice composing tens with ten frames to add to 20! Use this scaffolded EL Lesson alone or for more addition practice before teaching the Scavenger Hunt Addition lesson.

Advance your students from relative measurements to learning about standardized units with this lesson that teaches them about inches and feet by using common classroom objects.

Provide students with an opportunity to identify the wholes that are correctly divided into halves, thirds, and fourths (equal shares). Use this activity alone as a support lesson or alongside Cookie Fractions Fun.

Roll some dice to introduce the early concepts of associative and commutative properties in addition by composing and decomposing 10. Worksheets and a quiz are included!

Your students will turn boring number sentences into fun, Christmas-themed word problems! They will get practice with math and writing as they use their creative juices to write and solve single digit addition word problems.

Get your students synthesizing various subtraction strategies as they work with a partner to solve word problems. This lesson can be used alone or with the lesson plan Show Me the Money! Two-Digit Subtraction.

Double dominoes! Get your students excited to add with dominoes and playing cards. This lesson is a fun way to help your students continue to learn to add.

Practice finding unknown numbers in addition equations using fun and silly word problems.

It’s pizza time! Students will be introduced to the concept of partitioning shapes to create fractions that demonstrate halves, fourths, and eighths. This lesson is the first of two lessons that address second grade fraction concepts.

Introduce students to measurement with this fun scavenger hunt! Students practice measuring with string as they work in partners to develop language skills. Use alone or with the lesson Footy Fun!

Use this lesson to review three-digit addition strategies including base-ten drawings, number lines, and the standard algorithm.

Dive deep into word problems with this lesson that teaches students to sketch base-ten blocks to add multiples of 10 and two-digit numbers. Use alone or with the lesson plan Let's Build It! Two-Digit Addition.

Support your students' understanding of word problems as they invent strategies to add three addends in any order. Use this scaffolded EL lesson plan alone or with How'd You Get that Many?
