We have been very busy working on our Teddy Bear’s profile. The Teddies were all thoroughly exhausted after being subjected to ordering,  measuring of height and width using formal and informal units and also creating equivalence statements about the weight of our teddy bear. Here are some photo’s of the work we’ve been doing.

Today, we each adopted a woolly worm. We needed to measure how long our woolly worms were so we used the inchworms ruler. Students put the tails of the woolly worms on the start of the inchworm ruler and drew a line with a pencil where its head finished. We needed to ensure that the inchworms behaved themselves and remained straight while we measured them. We needed to give our woolly worms a name and record its length in “inchworms”. We got to keep our woolly worms which are actually very easy to take care of.

```Some people have discovered the power of doubling numbers. If your numbers get big enough, the zeros start adding up.
This is very important place value knowledge. Do you know what number comes after 999 trillions?```

Googolplex: The second largest number with a name. A "1" followed by a googol of zeros.

Googol: A large number. A "1" followed by one hundred zeros.```

2D has been learning about place value. We know that when we get to 9,  and we get one more, we need to make a bundle of “10”. Clever Mathematicians do this all the time. We also made “mega bundles” when we arrived at 10 bundles of 10- This is called “one hundred”.

Please ask your child to show you how the bundling system works and how to write numbers according to their hundreds, tens and ones. They should explain it like this: 156 has one of the hundreds, 5 of the tens and 6 of the ones. 1 hundred, 5 tens and 6 ones.

Mr Andrea can you put out some more harder maths activities?

• Mr Andrea says:

I’m just doing one now Chloe. Check out the most recent post following the compound words one. 🙂

• Chloe Miles says:

more pleeeeeeeeeeease

• Chloe Miles says:

pleeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeease

• Mr Andrea says:

I think you should think of some materials you might use if you were going to make an array of 100 Chloe. I’m positive you can find something around your house that can be arranged into an array of 100. You could then find some of the other arrays with this amount. Do you accept my challenge??

• Chloe says:

Challenge accepted!

• chloe says:

100 skittles

• chloe says:

20×5=100
5×20=100
1×100=100
100×1=100
50×2=100
2×50=100
4×25=100 25×4=100

Hi Mr Andrea, Heres a maths sum
60+60 = 120

• Mr Andrea says:

Thanks Chris hope you have fun tomorrow.

3. chloe says:

Hi Mr Andrea I was just wondering where the pictures of our teddies (because I would like to see them famous). AND! Also I’ve been having a fun time with them

• Mr Andrea says:

I’m having trouble uploading the photos from my Dropbox for some reason Chloe. Stay tuned.

4. Ella says:

Hi Mr Andrea,

I was exploring your blog and I found this maths section. It sounds like a fun activities for year twos! I would just wanted to let you know about my maths goal. I attempted all of those sums you gave me, I checked them on the calculator and they were correct. Even the hardest one!:19×15 I believe.is there anything else you want me to do over the weekend.

From Ella

• Mr Andrea says:

Depends how keen you are? The following website will generate as many two digit multiplication problems as there are atoms on planet earth. Generate some problems and work them out using a piece of paper and the algorithm instructions. Alternatively, enjoy your weekend.
