Lesson 1: Making Equal Groups: Today we are putting objects into equal groups. Find this video from week 2 lesson 3. 
Can you get some objects and split them into equal groups. You could take some sweets, some coins, your toys, etc. Practice saying: “ There are 4 equal groups of 3 OR there are 5 equal groups of 2.”
Lesson 2: Adding Equal Groups: Find this video from week 2 lesson 4 shows how to add equal groups together.
I used pasta made 3 equal groups with 10 pieces of pasta in each group. I can write this as 10 + 10 + 10.
If I count all my pieces of pasta, or if I count in 10s then I have 30 pieces of pasta altogether. (10, 20, 30)
Lesson 3: Making arrays to count in groups Watch this video 
to see how to count in arrays. After the video can you make some arrays and count the objects? Remember to arrange the objects in rows and columns like I did. They are easy to count if you arrange them in groups of 2, 5 or 10.
Lesson 4: Doubling: Watch the video by clicking on the butterfly picture
to see how I double some numbers. Can you make some lovely doubling butterflies like I did in the video? Draw a butterfly and fold your picture in half. Then open it up and put some spots on one wing with paint. Fold it in half again and press down. You should have double the number of spots now.
Lesson 5: Practice counting in 2s, 5s and 10s.
