Lesson Content

Day 1-2: Counting Numbers 1-300

Extending Our Counting:

• Review counting 1-100
• Learn to count from 101-200
• Practice counting from 201-300
• Learn number patterns: 100, 200, 300

Number Recognition:

• Show number cards and identify them quickly
• Practice reading numbers aloud
• Find numbers on a number chart

Day 3: Skip Counting

Skip Counting in 2s:

• 2, 4, 6, 8, 10, 12, 14, 16, 18, 20…
• Use this when counting pairs of things

Skip Counting in 3s:

• 3, 6, 9, 12, 15, 18, 21, 24, 27, 30…
• Use this when counting groups of three

Skip Counting in 10s:

• 10, 20, 30, 40, 50, 60, 70, 80, 90, 100…
• This helps us count quickly!

Day 4-5: Sorting and Classification

Grouping Objects:

• Sort bottle tops by color and count each group
• Group pencils by size and count
• Classify toys and count each type
• Use tally marks to record counts

Number Line Practice:

• Use a number line to find and show numbers
• Jump along the number line when skip counting

Examples in Class

Counting Example:

“Let’s count these chairs: Start at 1… 1, 2, 3… up to 25 chairs”

Skip Counting Examples:

• In 2s: “Count these shoes: 2, 4, 6, 8, 10” (5 pairs of shoes)
• In 10s: “Count these fingers: 10, 20, 30” (3 groups of 10 fingers each)

Sorting Example:

“Sort these colored blocks:

• Red blocks: 15
• Blue blocks: 12
• Yellow blocks: 8
• Total blocks: 15 + 12 + 8 = 35″

Exercises

Exercise 1: Number Recognition

Circle the correct number:

1. Two hundred and five: (205, 250, 502)
2. One hundred and thirty-seven: (173, 137, 317)
3. Two hundred and ninety: (290, 209, 920)

Exercise 2: Skip Counting

Fill in the missing numbers:

1. 2, 4, 6, ___, 10, ___, 14
2. 3, 6, ___, 12, ___, 18, ___
3. 10, 20, ___, 40, ___, 60

Exercise 3: Counting and Sorting

1. Count and group these items:
   1. ★★★★★ ○○○ △△△△△△△
   2. Stars = ___
   3. Circles = ___
   4. Triangles = ___

Exercise 4: Number Line

Use the number line to answer:

1. What number comes after 156? ___
2. What number comes before 203? ___
3. What number is between 145 and 147? ___

Exercise 5: Real-Life Applications

1. A basket has 125 oranges and another basket has 67 oranges. How many oranges are there in total?
2. In a school, there are 23 classes. If each class has 10 desks, how many desks are there altogether? (Use skip counting in 10s)

Fun Activities

• Number Hunt: Find numbers around the classroom
• Skip Counting Songs: Sing while skip counting
• Sorting Game: Sort classroom items and count them

Homework

• Practice skip counting in 2s, 3s, and 10s at home
• Count and sort items in your room
• Help parents count items while cooking or shopping

Assessment
