 # Groupings of Tens and Ones

1st Grade • Half Day Lesson Plan
\$6

## Lesson Plan Description

First Grade half day of math lesson plans containing 3 separate segments (30-60 minutes each) addressing Numbers in Base-Ten: groupings of tens and ones (1.NBT.2). These lessons include: practice counting and bundling tens and identifying remaining ones, making two-digit numbers using tens and ones, writing number sentences in expanded form to equal a number, writing numbers using tens frames, and a paper chain craft to create a visual representation of tens and ones.

• Segment 1: students will bundle objects into groups of tens and ones and then count by tens and ones.
• Segment 2: students will build a two-digit number using base-ten blocks, count by tens and ones, write a number sentence in expanded form for two-digit numbers, and draw a picture using base-ten blocks to represent a two-digit number.
• Segment 3: students will represent a two-digit number by filling in ten frames, write a number sentence in expanded form to equal a two-digit number in the ten frame, and will work in partners to create a paper chain to represent a two-digit number.

These lessons can be taught over the span of a half day or you can use the lessons independently, broken up over several days.
