5. YOU KNOW! TEXTUAL MATH PROBLEM ANSWER SOLUTION QUESTION CONDITION

6. 1. It calls word problem, because it is written by a text. 2. A textual math problem has a condition and a question. 3. That I know is in the condition. What I have to find is in the question. 4. I answer to the question of the word problem with the solution. 5. I have to write the answer of the math problem.

7. Solution: …………… Answer: 5 birds 4 birds alight on the tree, one bird – on the other tree. How many birds alight on the two trees? 1 + 4 = 5 Mark with a red colour a condition and with a green colour - a question of the math problem.

8. In the basket there are 10 apples and 5 pears. How many fruit are there? Numerical data are in the condition of the word problem. They are written by numbers. Numerical data help us to write the solution. Numerical data in textual math problem

9. A squirrel collected 10 acorns and four walnuts. How many fruit did a squirrel collect? 10 10 and 4 Numerical data in a word math problem can be written by words and numbers. Оh, where are they?

10. Colour a condition of M M M Math problem - blue, a question – red and numerical data – yellow. Some children planted 12 trees and eight bushes. How many trees and bushes did they plant? Exsellent

11. Solution: 6 – 4 = 2 (trees > mushrooms) ( mushrooms < trees ) To understand how much one number is LESS or MORE than other, we have to take out smaller number from the bigger. What do the words „more“ and „less“ mean in the textual math problem?

12. A child collected 12 chestnuts and 8 walnuts. How many the walnuts are less than the chestnuts? A child collected 12 chestnuts and 8 walnuts. How many the chestnuts are more than the walnuts? Word problems have the same conditions Word problems have different questions The solutions are different yes no
