The Victorian Curriculum states that Year Four students need to be able to model, represent and order numbers to tens of thousands. For the last two weeks this has been the focus of our Maths lessons.
We have had some great sessions using interactives to help consolidate and extend our understanding of place value. We have focused on understanding that each digit in a number holds a place and has value:
We have also been practicing writing numbers in three forms:
Some students are finding it tricky to remember that at times zero has a very important job at holding a place despite having no value.(Zero as a place holder-1b3ql7d). This is especially important as we read and write numbers that have 5 digits and more such 80 123 or 45 604. It would be good to practice reading, writing and expanding these numbers at home.
A fun thing we did in class was watch a YouTube clip like this one:
Then randomly I would press pause and the number that was on the screen, students had to read and record the expanded notation for. Have ago at home…
You might also like to use some of these websites for further practice (especially if you are having trouble with Studyladder)
Our next unit is focusing on ADDITION Strategies. You could practice up on your quick recall of basic number facts like 4 + 5, 9 + 9, etc.
