ESTABLISHING BEHAVIOR BOUNDARIES

Say, When we work together, I expect you all to carefully listen and do your best. Okay? When I am talking, you should be listening. And when I call on one of you to speak, we will all listen to you. That is how we show respect for each other. It is important that we respect each other so we can all do our best.

COUNTING WARM-UP

Let’s count around the group this time. Each of you will say the next number when it is your turn. I will start … 1. Point to the child to your right. Take a turn yourself.

MAGIC NUMBER ACTIVITIES (Magic Number is 2)

Cardinality

MATERIALS: Cardinality Chart, 3 interlocking blocks in a plastic bag

• Lay the Cardinality Chart on the table and say, This is a number chart. It has the numbers 1–10 across the bottom in a list. Run your finger across the numbers.
• Point to the number 1 and say, The first number is 1. Hold up 1 block and say, This is 1 block. How many blocks do I have?

• Put 1 block on the first block above the number 1 and say, 1 block.
• Point to the number 2 and hold up 2 blocks—one in each hand—and say, These are 2 blocks. How many blocks do I have? Wait for a response.
• Put the blocks together and say, 2 blocks. Then put them right above the number 2 on the chart.
• Say, As we go up the list of numbers on the number chart (gesture up the number list on the Cardinality Chart), we add 1 block at a time. It is like climbing up steps, 1 at a time.
• Hold up the Number Recognition Card 1 and say, What number is this? Wait for a response.

Number Sense Interventions Lesson 1

• Say, Now it is your turn! We are going to write a big number 2 in the air. Follow my finger. Ready? Copy me!
• Trace a number 2 in the air backward (about 18 inches high) so that the children will see it in the correct orientation. Say, Let’s try that again! Repeat twice.
• Say, Let’s play a game. I will hold up a card with a number on it, and I want you to tell me the name of the number. I will point to you when it is your turn, okay? Everyone else, say it in your mind, not out loud.
• Say, But, if the Magic Number comes up, I want everyone to say the number, even if it is not your turn. Pay close attention so you will know when our Magic Number comes up!

Error Correction

• If the children do not all answer for the Magic Number, then say, This is the Magic Number so everyone is supposed to answer. Let’s try that again! Hold up the number 2 and say, What number is this?

Finger Counting

• Let’s count to 2 on our fingers. Watch me. 1, 2. Demonstrate starting with index finger.
• Now let’s try on your other hand. 1, 2. Let’s try again. 1, 2.

PARTNERS OF 2 ACTIVITIES

MATERIALS: Pencil, Partner Dot Cards for 2, Dot Chart for 2, Number Sentence Cards Note: Do not use the words plus or equals until it is introduced in the activity.

• Put down the Dot Chart with 2 dots. Orient it horizontally.

Partners of 2 (1 + 1) Using Dot Chart for 2

• Say, See, here are 2 dots. 1, 2. Touch the dots as you count. I can break them into 2 parts with my pencil.

• Say, 1 and 1 is 2. Point to the dots when you say “1 and 1” and circle around the 2 dots when you say “2.”

• Say, We call 1 and 1 partners for 2 because together they make 2.

• Put down the 1 + 1 = 2 card and say, Here is another way to show 1 and 1. This is a number sentence. We call this plus. It means to put these two amounts together.

Review

• Put the 1+1=2, 2-1=1, and the 2-2=0 cards next to each other above the Partner Dot Card for 2.
• Say, Let's say these 1 more time. 1 plus 1 equals 2, 2 minus 1 equals 1, and 2 minus 2 equals 0.

STORY PROBLEMS

MATERIALS: 2 of each: pencils, erasers, crayons, blocks; Number Sentence Cards

• Say, Now I am going to tell you a story. Give a pencil to a child sitting nicely and say, (Child) has 1 pencil. His/her teacher gave him/her 1 more pencil. How many pencils does (Child) have now?
• Say, Here is another story. Give another child 2 crayons and say, (Child) has 2 crayons. The teacher takes 1 of his/her crayons. How many crayons does (child) have now?
• Hold up the 1 + 1 = 2 card and say, That is right because 1 pencil plus 1 pencil equals 2 pencils.

NUMBER SENTENCES ON FINGERS

MATERIALS: Number Sentence Cards

1 + 1 = 2

• Hold up the 1 + 1 = 2 card and say, Watch me do this using my fingers. Say, The first number is 1. This is 1 finger. Hold up your index finger on your right hand.

2 − 1 = 1

• Put the 2 − 1 = 1 card in front of you. Say, Watch me do this on my fingers. Say, The first number is 2. I will put up 2 fingers. Put 2 fingers up at once, not one at a time.

WRITTEN NUMBERS

MATERIALS: Lesson 1 Activity Sheet, pencils, crayons

• Say, Now we are going to practice writing numbers. Here is a paper with the numbers 0, 1, and 2 on it. I would like you to trace over the numbers with your pencil. Do your best to stay on the dotted lines, but do not erase if you make a mistake. Just try it again.
