  3. 看图写算式 10+2=12 只 2+10=12 本 15 - 3 = 12 15本

  4. 百位 十位 个位 11+4=15 4+11=15 15- 4=11 14 + 2 =16 15-11=4

  5. 计算 20 – 10 = 10 15 + 2 = 17 14 + 1 = 15 13 + 4 = 17 16 - 3 = 13 18 – 3 = 15 13 + 4 = 17 16 – 5 = 11 19 – 4 = 15 12 + 5 = 17 17 – 7 = 10 16 + 0 = 16

  6. 2+ 2+ 2+ 2+ 2+ 2+ 2+ 填空 10 11 12 13 14 15 16 17 12 13 14 15 16 17 18 19 我发现

  7. 19- 19- 19- 19- 19- 19- 19- 0 1 2 3 4 5 6 7 19 18 17 16 15 14 13 12 我发现

  8. 5 15 12 16 11 18 10 13 19 14 18 11 16 10 -10 +3 -4 +5 -7 +8 6+4 -6 +5 -4 +7 -5 +6 14-4

  9. 14 14 13 11

  10. 7、在 里填数。 17- 4 10+6 18- 5 16- 3 13 13+ 3 11+ 5 16 14 - 15- 2 1 12+ 4 8、小组讨论,可以怎么填? =12 =15
