Illuminations: Let's Count to 10

Let's Count to 10


Wrapping Up the Unit

Students review this unit by creating, decomposing, and comparing sets of zero to 10 objects and by writing the cardinal number for each set.

Learning Objectives

 

Students will:

  • Construct groups of zero to 10 objects
  • Identify the numerals from 0 through 10
  • Write the numerals from 0 through 10
  • Construct and decompose groups of zero to 10 objects
  • Record groups of zero to 10 items

Materials

 

Instructional Plan

Call the students together and choose three volunteers. Have the first student show a Numeral Card selected at random while the second student rings the bell the appropriate number of times and the third student writes the number on the board. Meanwhile, have the rest of the students show with connecting cubes the meaning of the numeral being shown. Repeat with other sets of three volunteers.

As the students respond, document their level of understanding on the Count to 10 Class Assessment teacher resource sheet. Determine which students need remediation and which students are ready to move forward. Plan additional experiences for those students who require additional support and extensions for those who need challenges.

Give each student connecting cubes and a copy of the Fill Up activity sheet.

Fill Up Activity Sheet Fill Up Activity Sheet

Tell the students that as you show a number [using numeral cards or the online Spinner], they should cover the corresponding number on one of the rows on the sheet with a connecting cube. Now ask a volunteer to show the numeral cards one at a time in random order, returning each card to the deck after it is called until all the numerals are covered. (A number may be covered only one time on the card.) Circulate to see which students are able to recognize and cover the corresponding numerals.

 

 

To end the unit, ask a student to make a train of 10 cubes and to show it to the class. Then have the student put it behind his or her back and break it into two pieces. Have the student show one part of the train and ask the other students to make a train as long as the visible part. Then ask them how many cubes they will have to add to make a train 10 cubes long. You may wish to encourage them to use 10 Frames as they do this. Repeat with other students.

Alternatively, or in addition to the above activities, students can work (either individually or in pairs) to review the numbers 1 through 10 by using the Concentration activity.

Concentration Activity Concentration Activity

To do so, students should select 1-10 under Levels, and either 1 or 2 players. In this activity, students match the numerals (1-10) with other representations explored in this unit.

Questions for Students

 


Show a train of 10 connecting cubes. Then take five connecting cubes from the train and cover the rest of the train. How many connecting cubes are left?

[Five connecting cubes are left.]
(Repeat with taking away other amounts from 10.)
Suppose you have 10 connecting cubes. Is this more or less than nine cubes?
[It’s more.]

Can you show that?
[Students should place a train of 10 side-by-side with a train of nine to see that 10 is one more than nine.]

Can you show me a group of 10? Can you show a way to split the group of 10 into two groups? Can you do it a different way?
Make two groups. Does one group have more? How many more?
How can you change a train of seven to a train of 10?
[Add three connecting cubes.]
(Repeat with other numbers.)

Assessment Options

 
  1. Use the teacher resource sheet, Class Notes, to document your observations about the students' abilities to do the following:
    • Construct groups of zero objects
    • Identify and write the numeral 0
    • Write the numerals up through 10
    • Construct groups of 0 to 10 objects
    • Record groups of 0 to 10 items
  2. Use the Show That Number Activity Sheet as a post-assessment in this unit.

Teacher Reflection

 
  • Which students met all the objectives of this unit? What extension activities are appropriate for those students?
  • Which students are still having difficulty with the objectives of this unit? What additional instructional experiences do they need?
  • Did all the students display understanding of the relationship between the numerals and the numbers? What is your evidence for this?
  • What were the greatest challenges for the students?
  • How can I help the students extend their understanding to numbers greater than 10?
  • What experiences can I provide so that the students will remember how to write the numerals?
  • What experiences can I plan so that the students will have a genuine need to write the numerals?
  • What learning experiences would help the students not yet comfortable with the concepts of 0 through 10?

NCTM Standards and Expectations

 
Number & Operations Pre-K-2
  1. Connect number words and numerals to the quantities they represent, using various physical models and representations.
  2. Develop a sense of whole numbers and represent and use them in flexible ways, including relating, composing, and decomposing numbers.
  3. Count with understanding and recognize "how many" in sets of objects.
