Maths Learning - Week 5

We have been super busy during our 10 minute hotspots with number knowledge. This weeks focus has been on squared, cubed and prime numbers. We have made revealers to learn with a buddy all the way up to 12 squared off by heart. We have been making our squared numbers out of counters to see our array has the same number of groups with the same amount in each. We used the '1's' place value blocks to build our cubed numbers, (which add another dimension). It was clear to see that our flat 2d shape/number was turning into a 3d shape, (because of the third dimension added).
Prime numbers are numbers that are only divisible by itself and 1. If a number has more than 2 factors, it is known as a composite number. We have been examining numbers to 100 to see if they are prime numbers or composite. In only a week, we have all made outstanding progress with our number knowledge learning that is supporting our strategy learning.

We are now ready to put our learning to action. We have been working hard using our place value houses to learn more about multiplying and dividing by 10, 100 and 1,000.

If we are multiplying, our number is getting bigger, larger, mutinying which means we move our number LEFT.

If we are dividing, our number is getting smaller/less which means we move our number RIGHT.

A morning of observations and wonderings!

Room 1 tamariki had an interesting morning observing and discovering what Matua Arthur had caught in his nets this morning. They were observing the eels he had caught-there were two types of eel, the long fin and the short fin eel. The tamariki could see two different types of shrimp, Inanga, Cadflys and an unknown insect we were having difficulty classifying.

It was observed that the long fin eel’s skin wrinkled as it slithered and bended, and the top fin started much closer to the eel’s head. The short fin eel’s fins started from the same position both on the top and bottom of its body and its head was flatter then the long fin eel allowing it to burrow their heads in the mud when droughts are present.

Matua Arthur sliced open an eel to see if it had eaten any whitebait. What arose from this was that it is possible for a science group in our class to look at the diet of the eels and compare the typical NZ food chain of an eel to that of an eel in our Whangawehi River.

There are many opportunities for Room 1 tamariki to carry out science investigations down at our Whangawehi River. So watch this space!!

Thank you also to Whaea Jenni for coming into class and talking to room 1 tamariki about what is required in a science investigation.

Science: what is it for?
