Let’s go through each doubles fact one by one. Doubles facts are when you add a number to itself — like 1 + 1, 2 + 2, up to 10 + 10.
We’ll check each card:
- 1 + 1 = 2 → That’s correct. One plus one is two.
- 2 + 2 = 4 → Correct. Two plus two is four.
- 3 + 3 = 6 → Correct. Three plus three is six.
- 4 + 4 = 8 → Correct. Four plus four is eight.
- 5 + 5 = 10 → Correct. Five plus five is ten.
- 6 + 6 = ? → The card shows eggs (maybe 12?), but the answer isn’t written. Let’s calculate: 6 + 6 = 12.
- 7 + 7 = 14 → Correct. Seven plus seven is fourteen.
- 8 + 8 = ? → The card has an octopus (8 legs), but the answer is cut off. 8 + 8 = 16.
- 9 + 9 = 18 → Correct. Nine plus nine is eighteen.
- 10 + 10 = 20 → Correct. Ten plus ten is twenty.
All the shown answers are right. For the ones that were missing (6+6 and 8+8), we filled them in correctly.
Final Answer:
All doubles facts from 1+1 to 10+10 are correctly solved as:
1+1=2, 2+2=4, 3+3=6, 4+4=8, 5+5=10, 6+6=12, 7+7=14, 8+8=16, 9+9=18, 10+10=20.
