Materials and Prep

• Pencil
• Blank paper

No prior knowledge or preparation is required for this lesson.

Activities

1. Activity 1: Mermaid Addition

   Draw or print out pictures of mermaids. Write addition problems on separate pieces of paper, such as "2 + 3" or "4 + 1". Place the mermaid pictures and the addition problems in a pile. Take turns picking a mermaid picture and an addition problem. Solve the addition problem and match it with the correct mermaid picture. Keep track of how many correct matches you make.

2. Activity 2: Mermaid Subtraction

   Draw or print out pictures of mermaids. Write subtraction problems on separate pieces of paper, such as "5 - 2" or "6 - 3". Place the mermaid pictures and the subtraction problems in a pile. Take turns picking a mermaid picture and a subtraction problem. Solve the subtraction problem and match it with the correct mermaid picture. Keep track of how many correct matches you make.

3. Activity 3: Mermaid Word Problems

   Create word problems related to mermaids. For example, "A mermaid caught 4 starfish and gave 2 to her friend. How many starfish does she have left?" Write down the word problems on separate pieces of paper. Solve the word problems using addition or subtraction, depending on the situation. Keep track of how many word problems you solve correctly.

Second Grade Talking Points

• "Today, we are going to have fun with math while learning about mermaids."
• "We will practice addition and subtraction using mermaid pictures and problems."
• "Let's solve addition problems by adding numbers together. For example, if we have 2 shells and find 3 more shells, how many shells do we have in total?"
• "Now, let's solve subtraction problems by taking away numbers. For example, if a mermaid has 5 pearls and gives away 2 pearls, how many pearls does she have left?"
• "Finally, we will work on word problems related to mermaids. These problems will involve addition or subtraction, and we will use our math skills to find the answers."
