Materials Needed

  • 1 toy clock or paper clock with movable hands
  • 10–20 small objects to count, such as blocks, buttons, or toy animals
  • Number cards from 1 to 10
  • Paper and crayons
  • A small bowl or bag
  • Optional: timer, tablet, or phone clock

Learning Objectives

By the end of the lesson, the child will be able to:

  • Count objects from 1 to 10.
  • Match a number card to a group of objects.
  • Use simple words to talk about time, such as now, later, morning, and night.
  • Ask and answer a simple “What happens next?” question.
  • Create a small number-and-time picture.

Success Criteria

The child is successful when they can:

  • Count at least 8 objects correctly.
  • Choose the number card that matches a group of objects.
  • Tell one thing that happens now and one thing that happens later.
  • Explain their picture using a sentence such as, “I see 5 stars at night.”

Introduction: The Curious Number Question

Adult says: “Today we are number detectives! Numbers can tell us how many things we have. Clocks can help us talk about when things happen. I have a curious question: What can happen now, and what can happen later?”

Show the child one object, then several objects.

Ask:

  • “How many do you see?”
  • “Which group has more?”
  • “What are you doing now?”
  • “What might you do later?”

Tell the child: “First, I will show you. Then we will practice together. Finally, you will be the number detective.”

Body

Part 1: I Do — Counting Carefully

Place 5 objects in a row. Touch each object as you count slowly: “1, 2, 3, 4, 5.”

Explain: “When I count, I touch each object one time. The last number tells me how many objects there are.”

Place the number card 5 next to the objects.

Quick Check: Cover the objects and ask, “How many objects were there?” Then uncover them and count together to check.

Part 2: We Do — Number Detective Hunt

Put number cards from 1 to 10 on the floor or table.

  1. Ask the child to pick a number card.
  2. Help the child count out that many objects.
  3. Place the objects beside the matching card.
  4. Count again together to check.

Think-Pair-Share: If another adult or child is present, have the child tell the partner, “My number is ___. I found ___ objects.” For homeschool, the child can tell a toy, stuffed animal, or family member.

Questions to ask:

  • “What number did you choose?”
  • “How many objects do we need?”
  • “What happens if we add one more?”
  • “What happens if we take one away?”

Part 3: I Do — Talking About Now and Later

Show the toy clock.

Say: “A clock helps us talk about time. Now means this moment. Later means after now.”

Use simple examples:

  • “Now we are counting.”
  • “Later we might eat a snack.”
  • “In the morning, we wake up.”
  • “At night, we get ready for bed.”

Move the clock hands to different positions. Do not focus on reading exact times unless the child is ready. Instead, use the clock as a visual reminder that time moves from one moment to the next.

Part 4: We Do — What Happens Next?

Act out a simple routine with the child:

  1. Put a toy in the bowl.
  2. Count the toy.
  3. Take the toy out.
  4. Put it in a “later” spot.

Ask:

  • “What are we doing now?”
  • “What will happen next?”
  • “What might happen later?”

Encourage complete but simple answers: “Now we count. Next we put it away.”

Part 5: You Do — Make a Number-and-Time Picture

Invite the child to choose one idea:

  • Draw 3 toys in the morning.
  • Draw 5 stars at night.
  • Draw 4 snacks for later.
  • Draw 6 people doing something now.

Ask the child to:

  1. Choose a number.
  2. Draw that many objects.
  3. Add a clock, sun, moon, or other clue about time.
  4. Tell you about the picture.

Prompt: “I see ___ ___. It is happening ___.”

Fun Movement Game: Now, Next, Later

Call out an action and have the child act it out:

  • Now: Clap 3 times.
  • Next: Jump 2 times.
  • Later: Pretend to sleep.

Let the child become the leader and choose the actions. Count each movement together.

Assessment

Formative Checks During the Lesson

  • Observe whether the child touches each object once while counting.
  • Ask the child to match a number card to a group of objects.
  • Ask, “What are we doing now?” and “What will happen later?”
  • Have the child show one more object and one fewer object.

Summative Demonstration

Give the child 8 objects and number cards from 1 to 10. Ask the child to:

  1. Choose a number card.
  2. Count out the matching number of objects.
  3. Tell whether the activity is happening now or later.
  4. Draw or explain what might happen next.

Differentiation

For Extra Support

  • Use numbers 1 to 5 instead of 1 to 10.
  • Count slowly while touching each object together.
  • Use sentence starters: “Now I am ___.” and “Later I will ___.”
  • Offer only two number cards at a time.

For an Extra Challenge

  • Use numbers up to 20.
  • Ask the child to make two groups and decide which has more or fewer.
  • Ask the child to create a three-step routine: “Now, next, later.”
  • Invite the child to draw a simple daily schedule with morning, afternoon, and night.

Closure: Tell What We Learned

Gather the objects and look at the child’s picture.

Ask:

  • “What did we count today?”
  • “What does now mean?”
  • “What does later mean?”
  • “What number did you use in your picture?”

Child recap: Encourage the child to complete these sentences:

  • “Numbers tell us how many ___.”
  • “Now means ___.”
  • “Later means ___.”

Final takeaway: “Today we counted objects, matched numbers, and talked about what happens now and later. You were a careful number detective!”

Optional Real-Life Practice

During the day, invite the child to count plates at snack time, count toys before cleanup, and describe the routine using “now,” “next,” and “later.”
