One car Five people one five times five equals five. One five makes five. 1辆小车5个人 1个5 1×5=5 一五得五 2. Two cars Five people two fives add two times five is twelve five ten. 2辆小车10个人 2个5相加 2×5=10 二五一十 3. Three cars Fifteen people Three fives add three times five equals fifteen thirty-five. 3辆小车15个人 3个5相加 3×5=15 三五十五 Four cars Twenty people Four fives add four times five equals twenty_______ 4辆小车20个人 4个5相加 4×5=20 ___________ 5. Five cars twenty-five people five fives_______ __________ 5辆小车25个人 5个5相加 ___________ ___________ 6. How many lanterns are there on the stage? 台上一共有多少个灯笼？ 7. To find the sum of four fives, you can add five plus five plus five plus five. 就是求4个5相加是多少，可以列加法算式5+5+5+5. 8. You can also write the multiplication 也可以列乘法算式。 9. You can use the formula "40, 50, 20" to calculate. 都可以用口诀“四五二十”来计算。 Part two 1. One person has a pole on his head, on which two people turn in circles. 1人头顶1根竿，竿上2人转圈圈； 2. Two people have two poles on their heads, on which four people turn in circles. 2人头顶2根竿，竿上4人转圈圈。 3. How many people are there on the three poles? How about four or five? 3根竿上有几个人？ 4根、5根呢? 4. First, give it a swing with the tools. 先用学具摆一摆。 5. Two plus two plus two is six，There are six people on the pole。 2+2+2=6,3根竿上有6个人。 6. What other questions can you ask? 你还能提出什么问题？ 7. How many lanterns are there in Taishan? 台山一共有多少个灯笼？ 8. I'm just trying to figure out what four twos add up to. 就是求4个2相加是多少。 9. You can write the addition formula.

A clown has three balls and four small bowls on his head. 一个小丑3个球，4个小碗顶在头； 2. Two clowns have six balls and eight small bowls on their heads. 2个小丑6个球，8个小碗顶在头。 3.

One clown three balls Tourism is three 1个小丑3个球 1个3 1×3=3 一三得三 Two clowns six balls Two or three to six 2个小丑6个球 2个3 2×3=6 二三得六… 7. What other questions can you ask? 你还能提出什么问题？ 8. How many people are dangling the board? 表演晃板的有多少人？ 9. How many bowls did three clowns head? Four, five? 三个小丑顶了几个碗？4个、5个？ 10. How many lanterns are there? 有多少个灯笼？ 11.

So let me figure out what three fives are, plus two. 我先算3个5是多少，再加上2个。 3. Five times three plus two is seventeen. 5×3+2=17 4. What else can I do? 还可以怎样列式？ 5. I'm going to make the fourth row five, so let's take four of them, what's the five, and then subtract three. 我把第四行也看作5个，先算4个5是多少，再减去3个。 6. Five times four minus three is seventeen 5×4-3=17 7. What other questions can you ask? 你还能提出什么问题？ 8. How many disks are there? 一共有多少个圆片？ 9. Try to solve the problem for yourself! 自己试着解决问题吧！ 10. Did I learn? 我学会了吗？ |
