   A. $13$

   B. $18$

   C. $17$

   A. $9$

   B. $0$

   C. $90$

11. Question 11

    1 mark

    What is $5+5$?

    A. $11$

    B. $9$

    C. $15$

    D. $10$

    (1 mark)

    Marking scheme

    D. $10$ — the double of $5$ makes a full ten. A and B are each one away, which is the usual slip.

12. Question 12

    1 mark

    Which of these numbers is the largest: $15$, $9$, $20$, $12$?

    A. $12$

    B. $20$

    C. $9$

    D. $15$

    (1 mark)

    Marking scheme

    B. $20$ — comparing them, $20$ is more than $15$, $12$ and $9$. It is also the only one with a $2$ in the tens place.

    A. $4$

    B. $3$

    C. $5$

    D. $6$

    (1 mark)

    Marking scheme

    A. $4$ — count back $6$ from $10$, or use the pair that makes ten: $6+4=10$, so $10-6=4$.

21. Question 21

    1 mark

    What is $3+4$?

    A. $5$

    B. $7$

    C. $6$

22. Question 22

    1 mark

    Count in tens: $10$, $20$, $30$, ___. What number comes next?

    A. $50$

    B. $35$

    C. $31$

    D. $40$

    (1 mark)

    Marking scheme

    D. $40$ — counting in tens adds $10$ each time: $30+10=40$. A skips a step by adding $20$.

23. Question 23

    1 mark

    What is $2+2+2$?

    A. $8$

    B. $5$

    C. $6$

    D. $4$

    (1 mark)

    Marking scheme

    C. $6$ — three lots of $2$: $2+2=4$, then $4+2=6$. This is also $3\times 2$. D stops after two of them.
