Arithmetic this morning is all about Fact Families. Fact families are inter-related addition and subtraction facts. Please answer the following questions and let me know how you get on in the comments!
Arithmetic Challenge – Today’s challenge links to our previous learning about doubling.
Please use the 2 minute timer and answer as many questions as you can in that time. Remember, you can comment your score or any you found tricky in the comment section! If these questions seem tricky to do mentally, try using a ‘number line’ from 0-20.

Next Step Challenge. What do you notice about the answers to the addition questions?
In maths we worked in partners to read and sort mixed addition and subtraction word problems. We underlined key information and phrases to help identify whether it would require an addition or subtraction operation to solve. These included: less, how many left, more, altogether.
This week in maths we have been measuring height and length. First we thought about the different between height and length and then practised using key vocabulary to compare lengths and heights including: longer, shorter, taller, longest, shortest, tallest. Next we used different non-standard units of measurement, such as cubes, paper clips and even our hands and feet, to measure different items around the classroom.
Finally we used rulers to measure the length of objects using centimetres. We had to remember to line the end of the ruler up carefully with the end of the object before we checked to see how many cms long it was.
I wonder if you can do any more measuring at home? What could you use to help you to measure?
