Free sample questions, a clear explanation, and 5 practice skills with an AI tutor that guides without giving the answer away.

Let's Be Addition All-Stars! ✨

Hi, super learner! Have you ever had a few yummy crackers and a friend shared some more with you? When you put them all together on your plate to see how many you have, you're doing addition! Addition is just a fancy word for putting groups together to find out how many there are in all. It's like making a team of numbers!

From Toys to Drawings 🧸✏️

Let's pretend we have 5 red blocks. Now, let's add 3 blue blocks. We can put them all in one big pile and count them: 1, 2, 3, 4, 5, 6, 7, 8. We have 8 blocks in all!

We can also show this with a drawing! Let's draw circles for our blocks:

🔴🔴🔴🔴🔴 + 🔵🔵🔵 = 8

We write this as a number sentence: 5 + 3 = 8. The + sign means "add" or "put together," and the = sign means "is the same as."

⭐ Key Takeaway!

Addition is just putting parts together to find the whole amount. You are a master at finding the "whole!"

Number Bond Buddies

A number bond helps us see the parts and the whole. For our blocks, the parts are 5 and 3. When we put them together, we get the whole, which is 8! Think of it like a little family of numbers that belong together.

Let's Create a Story!

Now it's your turn to be the storyteller for 4 + 3. Here’s an idea:

"There were 4 happy frogs sitting on a lily pad. 🐸🐸🐸🐸
Then, 3 more froggy friends hopped over to join them! 🐸🐸🐸
How many frogs are on the lily pad in all?"

To solve it, we can draw our frogs (or just circles!) and count them all up. Let's count: 1, 2, 3, 4, 5, 6, 7.
So, 4 + 3 = 7. There are 7 frogs in all!

You are doing an amazing job, Math All-Star! Keep finding things to count and put together!

Sample questions

1. Look at the apples! There are 3 red apples and 2 green apples. How many apples are there in all?

○ 3

○ 2

✓ 5
