Mathematics 2018-2019

Mathematics Blog
Check out our classes learning, test your times tables, read about the latest in the world of maths or use your resilient maths skills to solve different challenges. 
 The determination to learn new mathematics skills.
Making links between mathematical concepts and drawing upon prior knowledge to help.
The desire to be successful, looking for real life links and realising that learning is a continuous process.
 When faced with a difficulty, never giving up. 
Helping others through sharing expertise. 
Please check out this link to get an overview of how we develop children's mathematical understanding. We support the learning process by using concrete, pictorial and abstract steps to solidify different mathematical concepts. Two visual images that you will commonly see at Sandy Hill are the Part Part Whole model and Bar Model. See below for examples. 
This model shows that the part 5 and 2 equal the whole 7.
So... 5+2=7 or 2+5=7 or 7=5+2 or 7=2+5 or inversely... 7-5=2 or 7-5=2
However, the other model shows that the parts 2 and 3 equal 5. 
So... 2+3=5 or 3+2=5 or 5=2+3 or 5=3+2 or inversely... 5-3=2 or 5-2=3
Similar to the part part whole, the bottom of the bar shows the parts and the top shows the whole. 70+30 gives you the whole and demonstrates that the two together equal 100.
It also shows...100-70=30, 100-30=70
The bar can also represent multiplication/division learning. This bar shows that 3 lots of 9 equals 27. But can also show that 27 divided by 3 equals 9. 
Year 6 have been competing as a class to further speed up their times tables skills. All classes in the school log on to develop their fluency skills through a range of fun games and challenges. Every half term, Sandy Hill's classes take part in the Cornwall and Isles of Scilly competition.

Estimating angles on NRICH! Fantastic accuracy shown!
Reception have been practising their counting and number skills. The children are becoming really fluent with their numbers to 10: recognising them in many different contexts. 
The children in EYFS develop number understanding through a strategy called subitising. 
...but what is subitising? 
Have a read of NCETMs article to find out more about this fascinating approach to children's early number learning.
Active counting in the nursery: outdoor learning. 
Year 1 have been furthering their mathematics knowledge by using tens frames and part part wholes to identify number bonds to ten. The children have used manipulatives to further their understanding and associated them with abstract number sentences.
Times Tables
Knowing your times tables is like having the key to a palace. Times tables link to many areas of mathematics; being fluent and knowing your facts is amazing for children's confidence in mathematics. Check out this game below. 
Times tables actions help us remember the number patterns. 
Times tables actions are brilliant for remembering and having quick recall. Great job Year 3, who have become really confident with their 3s, 4s and 8s.  
Year 6 putting their quick fire times tables recall to the test in a team game of hit the button.
