Ten Ones to Make a Ten
Unit of Study: Making a Ten
Global Concept Guide: 1 of 2

2. Content Development
For this concept, students need to understand ten ones make a ten. Ten serves as the basis of our number system, therefore it is critical students have a strong understanding of ten.
At the end of this unit, students will have a conservation of the number ten. When counting with a ten frame, students will automatically recognize a filled ten frame represents ten.
Students need multiple opportunities with various maniupulatives to represent ten, such as ten frames, snap cubes, popsicle sticks, and two-color counters.

3. Day 1
With Adding to Make Ten, students will use ten frames and two-color counters to compose the number ten in various ways. Students will also determine if a given ten frame is more or less than ten.

4. Day 2
On day 2, students should have exposure to making ten without the assistance of a ten frame. For example, students can use other tools, such snap cubes and two-color counters.
With snap cubes, students can use two different colors to create a ten train. For example, a student can use three yellow snap cubes and seven green snap cubes to create a ten train.
See next slide for directions for Snap to Ten Investigation.

5. Day 2- Snap to Ten Investigation
Provide pairs of students a bag of different amounts of snap cubes. For example, bags can have 9 snap cubes, 15 snap cubes, etc (bags of cubes should range from 1-20). Each group will have to determine if the given set of snap cubes can make a ten, more than a ten, or less than a ten. If the given set is less than a ten, the students will have to determine the missing amount to equal ten. If more than ten, students must create a train of ten and use the language, one ten and five ones.
Students can record their responses in the Math Notebook.
For example:
More than 10
Equal to 10
Less than 10

6. Reteach/Intervention
For reteach, students will need more experience with ten frames to recognize a group of ten and understand ten ones make a ten. Students need experiences with other manipulatives, such as popsicle sticks, straws, or snap cubes.
Click on the video below for a sample remediation lesson with popsicle sticks. The student is asked to model numbers less than ten, but progresses to recognize a group of ten.

Go Math Chapter 6 pg. 237G RTI Tier 3- Pictures of 10: This intervention lesson focuses on the conservation of ten.
Animated Math Models (Skill 12) from Kindergarten Resources on Think Central provides students with a ten frame to create ten and recognize ten from sets.

7. Enrich
For enrichment, students should have experiences with creating a group of ten within problem solving situations.
Example- When ten-pin bowling, Larry knocked over eight pins. How many pins were left standing? (two pins are left standing)
Example- Darla set up 10 cans on the fence and tossed snowballs at them. First she knocked over 3 cans, then she knocked over 4 more. How many cans were left on the fence? (3 cans)
