Objective

By the end of this lesson, the student will be able to count up to 100 and understand the concept of addition and subtraction.

Materials and Prep

• Counting cards or flashcards with numbers 1-100
• Pencil and paper for writing

No prior knowledge is required for this lesson.

Activities

1. Counting Race: Set a timer for 1 minute and challenge the student to count as high as possible within that time. Keep track of their highest number reached and encourage them to beat it in subsequent rounds.

2. Number Line Hop: Create a number line on the floor using masking tape or draw one on a large sheet of paper. Call out a number and have the student jump or hop to that number on the line.

3. Missing Number Puzzle: Write a sequence of numbers on a piece of paper, but leave some numbers blank. Ask the student to fill in the missing numbers to complete the sequence.

4. Addition and Subtraction Game: Use the counting cards to create simple addition and subtraction problems. For example, show the cards for numbers 5 and 3, and ask the student to add them together. Repeat with different numbers.

Talking Points

• "Counting is a way of saying numbers in order. We start with 1 and keep going until we reach the highest number we want."
• "When we count, we can also write the numbers down. This helps us remember and keep track of what number comes next."
• "Sometimes we need to find a missing number in a sequence. We can look at the numbers before and after to help us figure out what goes in the blank."
• "Addition is when we put numbers together to find the total. For example, if we have 2 apples and we add 3 more, we have a total of 5 apples."
• "Subtraction is when we take away some numbers to find out how many are left. For example, if we have 7 cookies and we eat 2, we are left with 5 cookies."
• "Practicing counting, addition, and subtraction can help us become better at math and solve more complicated problems in the future."
