Get ready for some mental math! Help students practice subtracting by ten by solving real-world problems involving dimes.

Challenge your students to compare two methods for finding the least common multiple between two fractions. Use this lesson on its own or as support for the lesson Make It Work! Adding Fractions with Unlike Denominators.

Fractions can be tricky, but looking at them visually can help your students understand them. This lesson will help students with equivalent fractions, number lines, and making real world connections.

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.

Getting ready to subtract fractions? This lesson reviews how to subtract like denominators and teaches students how to subtract unlike denominators. The focus is on understanding the process and reasoning behind each step.

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.

Getting ready to add fractions? This lesson reviews how to add fractions with unlike denominators using number lines. Students will focus on understanding the process and reasoning behind each step.

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.

Take your understanding of factors one step further! Use this lesson to classify factors as prime and composite numbers while creating factor trees.

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