This unit packet includes modeling and identifying numbers 0-120. First grade students are beginning to understand the difference in place between two digit numbers and are able to represent two digit numbers using tens and ones. First grade students continue to “count on” by ones from any number and begin to count on by tens from any number:
10, 20, 30, …. Or 3, 13, 23,
Students also begin to understand place value, number word identification, different ways to model a number, 10 MORE 10 LESS, expanded form, and much more!!! In this packet you will find worksheets that require students to think critically and be able to identify numbers 0-120 using tens and ones.
This packet is Common Core aligned to the first grade standards:
The objectives for this lesson are:
IWBAT count by ones to 120 starting at any number.
IWBAT count by tens to 120 starting at any number.
IWBAT use models to represent tens and ones.
IWBAT group objects to show numbers to100 as tens & ones.
IWBAT read and write numbers to 120 and represent them as tens and ones.
IWBAT solve word problems using models and the count on strategy.
The SPM’s for this unit are:
2. Reason abstractly and quantitatively
4. Model with mathematics
5. Use appropriate tools strategically
6. Attend to precision
7. Look for and make use of structure
