Add It Up! Let's Practice Addition!

Today, we're going to become Addition Superstars! We'll practice putting numbers together to find the total. Get ready to count, think, and add!

Welcome students and introduce the lesson's goal: practicing addition. Ask them to share what they already know about adding.

What is Addition?

Addition means putting two or more groups together. We use the 'plus' sign (+) to show addition, and the 'equals' sign (=) to show the total.

Example: 🍎 + 🍎🍎 = 🍎🍎🍎 (1 + 2 = 3)

Explain what addition means using simple language and a visual example. Emphasize that it's about combining groups. Do a quick example with your fingers.

Strategy 1: Counting All

One way to add is to count everything! If you have 3 apples and I give you 2 more, you can count all of them: 1, 2, 3, 4, 5!

Let's try: 4 + 3 = ?

(Count together: 1, 2, 3, 4, 5, 6, 7! So, 4 + 3 = 7)

Introduce different strategies. Start with counting all. Have students practice with you using their fingers or objects.

Strategy 2: Counting On

Another way to add is to 'count on' from the bigger number. It's quicker!

For 2 + 5, start at 5 and count on 2 more: 5... 6, 7! So, 2 + 5 = 7.

Let's try: 6 + 4 = ?

(Start at 6, count on 4: 6... 7, 8, 9, 10! So, 6 + 4 = 10)

Introduce counting on. Explain it's faster. Do an example, starting from the larger number.

Time to Practice!

Let's try some together!

  1. 3 + 4 = ?
  2. 5 + 2 = ?
  3. 7 + 1 = ?
  4. 6 + 3 = ?

Provide a few practice problems for students to solve. Encourage them to try both strategies. Circulate and assist.

Your Turn! Worksheet Time!

Now you'll get a Addition Practice Worksheet to show what you've learned. Remember to use your counting all or counting on strategies. Do your best!

Explain the worksheet and what students need to do. Reiterate the use of strategies.

Great Adding, Everyone!

You did a fantastic job practicing addition today! Keep practicing these skills, and you'll be addition experts in no time!

Conclude the lesson, reminding students they are becoming great at addition. Encourage continued practice.

Answer Key

Addition Practice Answer Key

This answer key provides the correct solutions and a brief thought process for each problem on the Addition Practice Worksheet.

  1. 3 + 2 = 5
    Thought Process: Starting with 3 and counting on 2 more (4, 5) gives a total of 5.

  2. 4 + 1 = 5
    Thought Process: One more than 4 is 5.

  3. 5 + 3 = 8
    Thought Process: Starting with 5 and counting on 3 more (6, 7, 8) gives a total of 8.

  4. 2 + 6 = 8
    Thought Process: Starting with 6 and counting on 2 more (7, 8) gives a total of 8.

  5. 7 + 0 = 7
    Thought Process: Adding zero to any number keeps the number the same.

  6. 6 + 4 = 10
    Thought Process: Starting with 6 and counting on 4 more (7, 8, 9, 10) gives a total of 10.

  7. 8 + 2 = 10
    Thought Process: This is a common
