Illuminations: Let's Count to 5

Let's Count to 5


One, Two, Three--Go

After reviewing the numbers 2 and 3, students construct and identify sets of one. They compare sets of one, two, and three objects and record a set of three in chart form.

Learning Objectives

 
Students will:
  • construct groups of one, two, and three objects
  • identify and write the numerals 1, 2, and 3
  • compare sets of one with sets of two and three items
  • record a group of one on a graph

Crayons
Metal bowl
Canned whipped cream
Numeral Cards (photocopied onto cardstock)

Instructional Plan

Begin the lesson by having the students sings, "Catching a Fish." Next, teach the students to recite the nursery rhyme "Jack Be Nimble." Ask a volunteer to act out the rhyme by hopping over something [such as a stack of connecting cubes] that represents a candlestick. You may wish to use the student's name in the verse.

Ask, "How many students jumped?" [One] Can you hold up one finger? [Check to see that all the students can do this.] Then say the rhyme again with other student volunteers. Now tell the students to listen for the word "go," When they hear it, they are to clap their hands three times. Say, "One, two, three--go" and watch to see which students can clap three times. To extend the learning opportunity, call on volunteers to name a motion and say "One, two, three--go!" to indicate when to begin the motion.

Show the students the numeral 1, then give directions such as, "Wave one hand," "Stomp your foot one time," and "Blink one time." Next, tell the students you will show them a number and they are to drop that many counters into the bowl. Ask for a volunteer to begin, and show him or her the numeral 1. Ask, "How many counters will you drop into the bowl? [One] Encourage the other students to count as the counter is dropped. Call on several other volunteers to drop counters as you display the numerals 1, 2, and 3 in random order.

 

 

Now ask the students to look at the numeral 1, which you have displayed. (You may wish to use the numeral cards.)

Tell them that this figure means "one." Turn your back to the students and trace the figure in the air, then encourage them to do it with you. Sing the numeral writing song as you make the numerals named in the song. Now spray canned whipped cream on a plastic work surface and model how to draw the numerals 1, 2, and 3 in the canned whipped cream. Allow the students several minutes to do this. As you close this section of the lesson, you may wish to remind all the students to go to the numeral-writing station during the day to write "1," "2," and "3" in the sand.

Next, give each student a copy of the Numbers to 5 Activity Sheet and some counters.

Numbers to 5 Activity Sheet Numbers to 5 Activity Sheet

Ask the students to put as many counters into each section as the number indicates. (Although the numerals 0, 4, and 5 have not yet been discussed, some students may wish to try completing these sections as well. Alternatively, you can fold back these sections so they cannot be seen.)

 

 

After they have finished, give the students their Show How Many activity sheet.

Ask them to look for the column with a "1" at the top, and then to color in one row, starting at the bottom row. Circulate as they work. Encourage the students to compare the three colored rows.

 

 

Then collect the charts or tell the students to put the chart where it will be available for future lessons.

Questions for Students

 

What new number did we talk about today? Can you show me that many fingers?

[One; students should be able to hold up one finger.]

Can you count to three? What number did you say first? Next? Next?

[One, two, three.]

Show one finger. Now show one more. How many fingers are you showing now?

[Two.]

Show me a set of one and a set of two. Which group has more? How can you tell?

[The set of two has more.]

How can you change a group of two to a group of one?

[Take away one.]

When you count, what number comes after two? Before two?

[Three; one.]

How did you show "1" on your chart? What is different in the way you recorded one and the way you recorded two?

Where on the chart is the number 1? Can you point to the number as you say its name?

Listen as I ring this bell (or tap this drum or hit this triangle). How many sounds did you hear?

[One, two, or three.]

Can you find a "1" in the room? Can you find the number 2? 3? Where?

[Possible answers include on the clock, on the board, or on my paper.]

Assessment Options

 
  1. Reflecting on the students' understanding and skills will help you plan remediation activities for the students not yet reaching the lesson goals. This information will also be useful when planning extension activities for the students who have mastered the learning objectives.

Extensions

 
  1. Pose the following Challenge question: How can you change a group of three to a group of one?

Teacher Reflection

 
  • Which students have learned the meaning of each of the numbers studied so far? What are the next appropriate goals for them?
  • re there students still unable to count out one, two, or three objects? What should I do at this time to help them reach this goal?
  • Which students are not yet able to count by rote to five? What experiences do they need next?
  • Which students are not yet able to count rationally to three? What experiences do they need next?
  • Which students were able to identify the numerals to 3? Which can write all of them?
  • Which students were not yet able to write the numerals to 3? What instructional experiences do they need next?
  • Which students were able to compare a set of one with sets of two and three? Which students were not yet able to do this? What learning activities should I plan for them?
  • What adjustments will I make the next time that I teach this lesson?

NCTM Standards and Expectations

 
Number & Operations Pre-K-2
  1. Count with understanding and recognize "how many" in sets of objects.
  2. Develop a sense of whole numbers and represent and use them in flexible ways, including relating, composing, and decomposing numbers.
  3. Develop understanding of the relative position and magnitude of whole numbers and of ordinal and cardinal numbers and their connections.
  4. Use multiple models to develop initial understandings of place value and the base-ten number system.
