Now that your first graders have mastered numbers to 100, extend the counting sequence to 120 with this scaffolded lesson. Use this EL Support Lesson alone, or alongside the lesson plan 120 Steps.

BOOM! Have a blast teaching your students how to find and use patterns within the multiplication table to increase fluency with multiplication and build number sense.

Help your students understand rounding without rhymes or tricks. Students will use an open number line to round and then take part in a fun game that will get them moving around the room.

Build a solid foundation in number sense with this lesson all about the friendly number 10! Students will count with both fingers and base-ten blocks. This lesson can be used alone or with the lesson plan Place Value Concentration.

Let your students explore different strategies to figure out the missing number in an equation. Use this lesson on its own or as a support lesson for Missing Numbers: Math Review.

Let’s start building numbers! Just as building skyscrapers is a visual representation of mathematics, students will use the visual representation of base-ten blocks to add—or build—onto a two-digit number.

Every student can be a magician after this lesson in mentally adding and subtracting by 10. No previous magic training required!

Why make things harder on ourselves? Teach your students to decompose numbers to make math easier! Use this as a stand alone lesson or a pre-lesson for Decompose to Multiply: 6, 7, 8, and 9.
