## Building Numbers Up to 10

• Lesson
Pre-K-2
1

Students construct sets of numbers up to 10, write the numerals up to 10, and count up to 10 rationally. They use ten frames and also make bean sticks.

To assess prior knowledge, give each student a blank piece of paper. Display Numeral Cards from 0 to 10 in random order and ask the students to draw sets of objects that match the numeral displayed.

 Numeral Cards

Observe and document the names of those students who consult resources in the room that help them complete the task, as this might demonstrate a lack of understanding.

Ask students to share their drawings with the class.

To begin the lesson, ask students if they have ever heard the expression "High Five." Tell students that they will use a variation of that greeting by making High Sixes, Sevens, Eights, Nines, and Tens.

To demonstrate its meaning, "High Ten" the student to your right. Hold up both of your hands with fingers extended upward to that student and say "High Ten." The student should touch the palm of your hands with his or her palms.

Ask that child to name a "High" number from 5 to 10 and greet the student next to him or her by extending the correct number of fingers upward and touching palms. That student will name a number and greet the next student, and so on around the circle.

Next, give students paper and crayons and have them work in pairs to trace both hands with the fingers outstretched, then label the tracing "10."

Call on 11 volunteers and assign each a number between 0 and 10. Ask them to make a numeral card for their assigned number. Collect and shuffle the numeral cards.

Next, put out connecting cubes, and then show the students a numeral card. Say, "Put this many cubes, one per finger, on the tracing you just made. Then make a tower with the cubes and lift it in the air."

Ask them how many stories are in the tower. Repeat with the other numeral cards 0 to 10, in random order.

When they can comfortably make towers for the given numbers, show two numeral cards, for example, 6 and 10. Ask the students to make two towers and compare them. Next, ask students to share their comparisons with the class using descriptive vocabulary.

Comparisons might include:

10 is greater than 6
10 is 4 more than 6
6 is 4 less than 10

Ask students to look at a numeral card you have displayed. Review with the students how to make the numeral. Turn your back to the class so that you will be writing in the same orientation as the students. Then trace the figure in the air with large strokes. Encourage the students to do this with you.

You may find the Suggestions for Numeral Writing Teacher Resource Guide helpful for students who are having difficulty writing the numerals.

As a take-home record of this lesson, or as an entry in their learning portfolio, have the students lay two towers on a piece of paper, trace around each tower, and write the numerals for each under them (as shown below). Encourage students to write a comparison of the towers in words and/or symbols.

Give each student a copy of the Ten Frames activity sheet.

 Ten Frames Activity Sheet

Ask students to model each number you show by placing one counter per section in the Ten Frame, beginning at the smiley face and moving in the direction the arrow is pointing until the top row is full.

Display a numeral card and observe the students as they place the connecting cubes. Ask them to remove the cubes before they model the next number.

The ten frame uses the concept of benchmark numbers (5 and 10) and helps students develop visual images for each number. For example, this device makes it easy to see that 6 is 1 more than 5 and that 6 is 4 less than 10.

You may wish them to write each number as they model it in the ten frame.

Students may also use the Ten Frame tool to explore numbers up to 10.

 Ten Frame Tool

Now distribute three craft sticks, white glue, and pinto beans to each student. Have the students glue 10 beans on each stick, spacing them equally in two groups of 5.

The inventor of bean sticks, Bob Wirtz, suggested this placement so that students would be aware of the relationships of numbers to the benchmark numbers 5 and 10. He used this same principle when he invented the ten frame.

Ask students to make three sticks, each with 10 beans, and then bring the sticks to you. As you receive each stick, ask the student to check that the number of beans is correct, then have him or her lay another layer of white glue across the beans. The glue will dry clear and will make the bean sticks more durable. Put the bean sticks on a table or a windowsill to dry and tell students they will use them in future lessons.

Assessments

1. The Questions for Students will help you assess students’ levels of knowledge.
2. Use the Class Notes sheet to document your observations about students’ understanding and skills. You may find this information useful when discussing student progress toward the lesson objectives with students, parents, administrators, and colleagues.

Questions for Students

1. What numbers did we talk about today?

[0 to 10.]

2. Pick a number. Show me that many fingers. Show me that many cubes.

3. Can you find the numeral card that shows that number? Count out loud to that number. Write that number.

[While technically what we write is a numeral, not a number, this distinction is not necessary at the early grade levels.]

4. How did you show this number on the ten frame? Make a ten frame, which shows how many fingers I am holding up.

Teacher Reflection

• Which students were able to stay on task when they worked in the whole group setting? Are there any changes in seating I should make?
• Which students were able to stay on task when they worked independently? What experiences are necessary for those who could not?
• Which students could count to 10? What experiences are necessary for those who could not?
• Which students are able to identify the numerals to 10? Which could write all of them? What practice is needed for those who cannot identify them?
• Which students could use the ten frame to show the meanings of numerals up to 10? How can I help those who cannot do this yet?
• What adjustments will I make the next time I teach this lesson?

### Building Sets of 11 and 12

Pre-K-2
Students use bean sticks, connecting cubes, and ten frames to construct sets of 11 and 12, record them, and compare them.

### Building Sets of 13 and 14

Pre-K-2
Students construct and identify sets of size 13 and size 14. They compare sets to sets of size 13 and size 14, and record the number in the sets. They decompose a set of 13 and a set of 14 in several ways.

### Building Sets of 15 and 16

Pre-K-2
Students explore the numbers 15 and 16. They make and decompose sets of size 15 and size 16, write the numerals 15 and 16, and compare other sets to sets of size 15 and size 16.

### Building Sets of 17 and 18

Pre-K-2
Students construct sets up to size 18, write the numerals 17 and 18, and model 17 and 18 with bean sticks, cubes, and ten frames.

### Building Sets of 19 and 20

Pre-K-2
Students explore sets of 19 and 20. They count up to 20, construct and decompose sets up to 20, and record the decompositions.

### Learning Objectives

Students will:

• Construct groups of 0 to 10 objects
• Identify and write the numerals 0 to 10
• Record the number of objects in groups of size 0 to 10
