2025年晨光智学同步指导训练与检测一年级数学上册人教版第108页答案
一、算一算。
$6 + 9 = $ $9 + 4 = $ $8 + 8 = $ $6 + 5 = $
$3 + 9 = $ $5 + 4 = $ $5 + 7 = $ $8 + 5 = $
$7 + 7 = $ $4 + 8 = $ $3 + 7 = $ $9 + 9 = $
$7 + 8 = $ $9 + 7 = $ $6 + 7 = $ $9 + 5 = $
$11 + 8 - 3 = $ $18 - 4 - 4 = $ $9 + 8 - 7 = $

答案

1. $6 + 9 = 15$
2. $9 + 4 = 13$
3. $8 + 8 = 16$
4. $6 + 5 = 11$
5. $3 + 9 = 12$
6. $5 + 4 = 9$
7. $5 + 7 = 12$
8. $8 + 5 = 13$
9. $7 + 7 = 14$
10. $4 + 8 = 12$
11. $3 + 7 = 10$
12. $9 + 9 = 18$
13. $7 + 8 = 15$
14. $9 + 7 = 16$
15. $6 + 7 = 13$
16. $9 + 5 = 14$
17. $11 + 8 - 3 = 16$
18. $18 - 4 - 4 = 10$
19. $9 + 8 - 7 = 10$
二、看图列式计算。

答案

1. $4 + 4+ 2=10$(面)
2. $13 - 3 = 10$(颗)
3. $6 + 9 = 15$(个)
4. $12 - 4 - 2 = 6$(个)
5. $3 + 3+ 2 = 8$(人)
6. $3 + 4+ 4 = 11$(只)
