Add up to 20

Using any whole numbers as many times as you like make each line of the rectangle add up to 20.

Can you find more than one way to do this? Can you make up your own puzzle like this?

14 3

9

4



Add up to 20 - answer

Now the key to doing this is to look at the top row. The numbers 3 and 14 add up to 17 which only leaves 3. So the two numbers must be 1 and 2 - try them to see where they fit best.

14 3 1 2

Not three in a line!

This 3 x 3 square has three counters in it in a row.

And then...how many counters can you put in a 4 x 4 square without getting three in a row!

But what I want to know is how many counters you can place without getting three in a row! You can have one or two in a row but not three!



Not three in a line - answers

You can place a maximum of six counters in a 3 x 3 grid without getting three in a row.

There is more than one way of arranging these 6.

You can place a maximum of eight counters in

a 4 x 4 grid without getting three in a row.



Ten tents

A little bit of logical thinking needed for this one, I think! Each letter is worth a number of points. The points are added up to make the total for the word. Try to work out the number of points for each letter and then find the value of the last word.

TEE = 4

TEN = 6

NEST = 10

TENTS = ?

How many points would TENTS get?

Clue: think about the

double E !!



Ten tents - answers

TEE = 4

TEN = 6

NEST = 10 TEE = 4 T can not be 1 because EE can not add up to 3. T can not be three because EE can not add up to 1. So T must be 2. If T is 2 then E must be 1 to make TEE add up to 4. If T is 2 and E is 1, then N must be 3. (ten = 6) This means S must be 4 to make NEST add up to 10. So TENTS = 2 + 1 + 3 + 2 + 4 = 12

Remember the clue: think about the double E !! Get this and you will crack the answer!

Well done everyone who got the correct answer!

Well the clue should have helped. Let's take a look:
