Answer:

Explanation:
The children selected the number 6,
Wrote the number 6 in the blank
After adding some more oranges to the basket it has 16 oranges now
Subtract 6 from 16
16 – 6 = 10
Therefore, 10 oranges were added to the basket.

Children work in pairs. Have one child choose a number from 6 to 9. Tell them this is the number of oranges in a basket and have them write their number. Then tell them that more oranges are added to the basket and now there are 16 oranges in the basket. Have them find how many oranges were added and draw to show what they did.
