A 400km Journey...

Come check out the model...

For maths on Thursday, we investigated a problem for a 400km journey to Wellington. The journey actually is approximately 300km, but we took an extra 100km of detours.

The problem was to find out fractions of the journey on a number line. So how far had we traveled to reach 1/2 of the way there? Or 3/4 and so on. Many of us needed materials to help us to see it, so we got out the tens place value blocks. 40 x 10 = 400 km. Each cube on the ten block = 1km. So 20 blocks was half of 40 blocks and it represented 200km. Half of 400km is 200km. And so on. Jack took some photos of our model.

40 km is 1/10 of 400 km

50 km is 1/8 of 400km

Hi Taylor!

We have reached halfway!

1/5 of 400km = 80km, so 2/5 = 160km

300km, 3/4 there.

The real journey is 296km...

Two Problems Involving Fractions

We are so busy with the Production at the moment but here is a maths post especially for you. Add a comment (text, voice or drawing) to our Voice Thread!

Decimals on a Number Line

Look at how Tash, Flossie, Jake and Sami answered this problem. Their answers are different. Are they right. Why?

Fractions With The Pacs

Check out this video! We were working out what we know and understand about fractions. The Pacs wrote fractions on a card and pegged them up on our number (washing) line. They did very well!
