Help your child in Grade 2 build an understanding of multidigit numbers, addition, and subtraction with these animal-based activities.
Activity 1: By the sea
This project uses the context of sea-related organisms to build an understanding of multidigit numbers. Your child will write their own 2-digit numbers to tell the number of fish, shells, or birds they might find in, above, or by the sea.
On pages 2 and 3, your child will write how many tens and ones are in their numbers.
On page 4, your child will compare numbers.
Your child can model the numbers on each page with quick pictures, with a stick representing a ten and a dot representing a one.
Materials needed
- Crayons or colored pencils
- Teacher guide
- Student sheet
Print the pages of the student sheet and fold the pages in half to make a storybook. Have your child write their work on the printed pages.
Extend the lesson
Read a book about fish or other sea organisms, take a virtual tour, or view information online about sea life.
As you gather information, count each type of organism you see and compare the numbers. Select one organism and write a story about that creature.
