We worked hard in Maths this week, checking our understanding of place value using MAB blocks and swopping them to compare their values.
Look at these pictures of MAB blocks and the video where Harper explains how to compare them on the worksheet.
So, if the number is 2 543. There are 2 x 100s, 5 x 100s, 4 x 10s and 3 x 1s.
If we run out of 1 000s, then we have to swop ten hundreds for each 1000. So we would have 2000 which means 10 x 100s + 10 x 100s = 20 x 100s plus the 5 x 100s we already have, so it would be: 25 x 100s, 4 x 10s and 3 x 1s.
If we run out of 1 000s and 100s, then we have to swop 10s for the 2 000 and the 500. We would have: 254 x 10s and 3 x 1s
If we are only counting in 1s then we would have 2 543 ones.
Harper explains how to swop between them to make the exact same number in this video.
Now have a go at the worksheet which you will find in your Connect Classroom soon. See if you can do it in the Word document and send it back to me using the SHARE button in your Office 365. Otherwise, I have included a PDF here too. Print it out, then you can scan it and send it to me through e-mail or by using the SHARE button in your Office 365.
