This week some of us have been breaking whole numbers into tens and ones (partitioning) making our numbers with the Numicon and writing about what we have made. We have also had number talks and these are useful to try at home for all children.
write a number
make a number
number before? Number after?
how many tens? How many ones?
add a ten. Subtract a ten
odd or even? How do you know?
Number talks help improve our speed of calculation, our ability to use mathematical language and the visualisation of mathematical processes.
Some of us have been improving our speed and accuracy with addition and subtraction ‘chimney’ calculations and applying these to problem solving. We have been working on more challenging fact family problem solving, using our knowledge of inverse operations (7+3 = 10 10-3 = 7 etc as a very simple example) to find missing numbers and write number sentences. We have been using the part, part, whole method in the attached photograph and this can easily be recreated at home.
You can find lots of games and challenges on Topmarks Maths to build up speed, confidence and accuracy Lots of verbal practice of mental maths skills is also useful.
