Coordinating our thinking

Knowing exactly where things are on a coordinate grid using Numicon resources has been working well in class this week. We have been using the 100 boards with Numicon tiles to help us fully understand which is the X axis and which is the Y axis. 

Recording the coordinates for symmetrically placed tiles has made us think very carefully as the coordinates (8,4) are entirely different to the coordinates (4,8). 

Double checking what we have written down is always a good idea too. We have also been talking about real life examples of when you might need to understand coordinates such as when you are reading a map or when archaeologists are digging a large area. 

What goes in the box?

Solved it ...

Being given the answer and asked to find the question really helps to develop a deep understanding of the mathematics involved in calculation. When faced with empty boxes for three two digit numbers Marcus took the time to carefully read the question which ensured that he did as the question stated and only used the digits 1 and 9. 

 He then went on to give a clear explanation of exactly how he arrived at his correct  answer. Empty box questions are just a challenge to be met head on by this young man.

and can explain how I did it.

Multiplying and Dividing by 10

13 X 10

 Knowing how to multiply by 10 is what we have been working on recently. Using our practical resources along with a place value grid has really been useful so we physically show what is happening when we are thinking about our calculations.

= 130

As division is the inverse of multiplication we have also been working on dividing by 10.

320 ÷ 10

= 32

The quick way to maths websites

In Ganges class we often use maths resources to help in developing our learning. Now we have tablet computers we can get straight to the websites we need for particular lessons even quicker. Once we are given an OCR (optical character recognition) code all we have to do is use the OCR app on the tablet and then 'Hey presto' we are right were we need to be and are able to get on with our maths work. 

Multiplication Fun

Creative thinking and maths are often a great combination. As we develop our multiplication skills we have been using Cuisinaire rods to help us actually see what certain calculations look like. As you can see some of us were thinking about winter and some others let our mind move to our favourite football team. Let's hope Everton don't try a 151 formation in a match!

The New Year in Numbers

HAPPY NEW YEAR!

Ganges class began the term by turning their active minds to coming up with all manner of different facts about the number of this New Year. Did you know the highest number we can make from the digits 2015 is 5210 or even that if we round this year up we leap forward to 2020? We were all very pleased to come up with so many interesting facts based on just one four digit number.
