“What does maths have to do with learning English?” you might ask. Many people believe that nothing. In fact many wrongly believe that you can be good either at maths or at English.

However, I think that mathematics and English have more in common than it might seem at the first sight. To be good at both of them you have to practise a lot. And to be able to solve the mathematical problem you have to understand it. And to understand the mathematics you need to understand the English first. Thus English and algebra have a lot in common.

[showmyads] As I write above, to get to the algebra you need to understand the English first. Learn the following vocabulary using the mind map. All the words are explained and demonstrated. Print out the mind map and write the translation of the words into the empty boxes.

Now it is time to practise the vocabulary you have learnt in the mind map. If you pass the vocabulary quiz you can play the game Tic_Tac_Toe. Both of the activities are in HTML 5 so you can try them out on your mobile phone or tablet. There is just one way to win the Tic Tac Toe game. Can you find it? Good luck.

Mathematic problems – vocabulary Now that you know all the vocabulary it is the time for the algebra. Can you solve these problems?

1. There is a big container full of lemonade. You can fill 114 bottles from this container. Each of these contains 0.7 litre. How many 0.3 litre bottles can you fill from the same container?

2. A restaurant bought 6.4 kilogrammes of pork, 3.5 kilogrammes of beef and 4.2 kilogrammes of ham. One kilo of pork costs 123 crowns, one kilo of beef costs 245 crowns, and one kilo of ham costs 156 crowns. How much did the restaurant pay?

In the evening his father gave him $2.70 and he returned $5.00 to his mother. How much money did he have at the end of the day? Did he have more or less money and by how much?

Here you can see the graphical explanation how to solve the mathematical problems.
