Activities

1. Activity 1: Selkie Addition

Write down five addition problems related to selkies. For example, "If there are 3 selkies on one rock and 2 more join them, how many selkies are there in total?" Solve each problem using the traditional addition method.

2. Activity 2: Selkie Subtraction

Create five subtraction problems involving selkies. For instance, "If there are 7 selkies swimming in the ocean and 3 of them go back to their caves, how many selkies are left in the ocean?" Solve each problem using the standard subtraction method.

3. Activity 3: Selkie Word Problems

Think of three word problems related to selkies that involve both addition and subtraction. For example, "There are 5 selkies playing on the beach. If 2 more selkies join them and then 3 selkies leave, how many selkies are left playing on the beach?" Solve each problem step by step, explaining your reasoning.

Second Grade Talking Points

• Selkies are mythical creatures from Scottish and Irish folklore. They are said to be able to transform from seals into humans.
• Today, we will be using selkies in our math problems to make them more interesting!
• When we add selkies, we are combining them. For example, if we have 2 selkies and add 3 more, we count a total of 5 selkies.
• Subtraction is when we take away or remove selkies from a group. If we have 7 selkies and 3 of them go away, we are left with 4 selkies.
• Word problems are stories that we need to solve using math. We will read a story about selkies and figure out how many selkies are involved in the situation.
• Remember to think carefully and use the addition or subtraction method we have learned to solve the problems.
