Learning objectives

• You will get to know the method of creating a pattern for solving a word problem.

• You will get to know the method of producing and solving word problems.

Learning effect

• You will learn to create a pattern for solving a word problem.

• You will learn to produce and solve word problems.

Recollect the order of operations in multi‑stage arithmetic expressions. Give examples of the most common calculation mistakes. Think and give examples of everyday life situations, in which you use skills connected with addition, subtraction or multiplication. Form short tasks leading to these types of calculations.

This type of tasks is called word problems by mathematicians. The aim of the class will be getting to know methods of solving them. Draw a timeline and mark some important moments in your life on the timeline. Using this information, produce two word problems and solve them. Create a pattern for solving word problems.

The pattern for solving word problems.

1. Read the problem carefully.

2. Write down the given information, what is knownknownknown and unknownunknownunknown – you can make a picture or a diagram.

3. Do the calculations and write them down.

4. Check if the result meets all the requirements of the problem.

5. Write down the answeransweranswer.

There are many ways of solving word problems. For example, by writing and performing appropriate operation or graphically.

Use the information to solve the tasks.

Having finished all the tasks, do the consolidation tasks. Write down the information you should remember.
