Textual math problem

In autumn 2 red and 3 yellow leaves fell down from the tree.How many leaves fell from the tree?

What is a textual math

problem?

This is the CONDITION of textual math problem.

How many fruit are there in the basket?This is the QUESTION of Math problem.

There are 2 pears and 3 apples in the basket.

What I know is in the condition of the textual

math problem.

In the question is told what I have to find.

There are 2 flowers and 3 trees on the meadow.How many flowers and trees are there on the meadow?

2 + 3 = 5This is the SOLUTION of

textual math problem.

At last we have to write the answer of textual math

problem.

ANSWER: 5 flowers and trees

TEXTUAL MATH PROBLEMANSWERSOLUTIONQUESTIONCONDITION

I KNOW!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.

Let`s check what have you remembered!

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.

There is numerical data in each textual math problem.

Solution: 10 + 5 = 15 Answer: 15 fruit

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

Who has recognized correctly numerical data in the word problem?

Solve it.

A squirrel collected 10 acorns and four walnuts. How many fruit did a squirrel collect?

Ani: 10

Bobi: 10 and 4Solution: 10 + 4 = 14

Answer: 14 fruit

Numerical data in a word math problem can be written by

words and numbers.

Оh, where are they?

Check what you remember!

Colour a condition of 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?Solution: 12 + 8 = 20

Answer: 20 trees and bushes

Exsellent

Кatya drew 4 mushrooms and 6 trees. How many mushrooms are less than the trees? How many trees are more than the mushrooms?

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?

Compare the word problems.

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?

Solution: 12 - 8 = 4 Answer: 4 chestnuts >

Solution: 12 – 8 = 4Answer: 4 walnuts <

Mimi ate four cherries. Her brother ate 2 cherries less than Mimi. How many cherries did Mimi`s brother eat?

Mimi ate four cherries. Her brother ate 2 cherries more. How many cherries did he eat?

Solution: 4 - 2 = 2 Answer : 2 cherries

Solution: 4 + 2 = 6Answer: 6 cherries

Word problems on the picture

Use the picture and solutions next to it. Make the word problem.

There were 8 birds on the tree. Five stayed on the tree. How many came down on the land?

There were 8 birds on the tree, three - came down under the tree. How many birds stayed on the tree?

8 - 3 = 5

5 birds alighted on the tree, and 3 - on the land under the tree. How many are the birds in all?

5 + 3 = 8

8 – 5 = 3

Our holiday, devoted to the book, nature and mathematics and we deserve the best assessment.

Bravo! You know how to solve Math word problems for the

gifts of the nature!

A Presentation – lessonIs developed by ideas for

math word problems , connected to the title of the project „More trees?

Yes, please!“ of Math book for FIRST GRADE. Authors: Yuliana Garcheva, Angelina Manova, Reni Rangelova,

Rumiana Petrova.The lesson is realized with students from 1st grade, SOU „Ivan Vazov“,

Pleven, Bulgaria, who are taken a part in mathematical competitions and who

have won awards and prizes.
