Multiplication Pyramid

WALT: Complete the pyramid using no calculator.

This week for an exercise for our brain, we completed a multiplication pyramid. Usually our teacher allows us to use the calculator for the top three numbers. Instead of that, she made us work it out on our own. That's exactly what I did. I did use the calculator to check the answers but not multiply. My working out is on the side of the pyramid in the google drawing.

Multiplication Pyramid

WALT: Practice our multiplication.

Most weeks we use the Multiplication Pyramid to get our brains started for the week. How it works is...

when you first get there are only the bottom layer of number, multiply the numbers and put the answer in the top box. For example, in the bottom left corner of the pyramid the multiplication equation would be... 5 x 1. My answer is in the box above.

WALT: Practise our multiplication.

This week in maths we had a pyramid to multiply. So how it works is the you multiply the first row. For example, 9 x 2 on the right hand bottom corner. That would equal to 18. 

12 x 12 Grid

WALT: Practise our 12 x 12.

Today we did our daily 12 x 12 grid. Everyone had ten minutes to do it. I really proud of myself because I finished at 7 minutes and 7 seconds. That's my record. It may not be as fast as others, but I think its a good time. Can't wait to try and beat tomorrow.

Fraction Word Problems

WALT: Finish the follow up activity.



Our task was to...

1. Make sure you read the questions in full before attempting to answer them.
2. Highlight the important parts of the question.
3. Make sure you show all working.

I did all of this. Some may be wrong but I really did try my best. I found the question on slide number four. How I solved it was by...

Taking the information and using it. Like this;

This would have been really helpful if we had a presentation this week. But I've already finished it and now I just needed to post this.

Multiplication Pyramid

WALT: Practise our multiplication.

This week we had a follow up activity. We had to multiply the bottom row then work our way up. I found this very fun. My friends and I had fun trying to work it out the fastest. The top number took a while to found out. 

Multiplication Pyramid

WALT: Find a rule to a sequential pattern

For this activity, we used our multiplication skills to find out the top number.  As you can see the numbers keep getting bigger and bigger.  How this pyramid works is that the numbers next to each other is multiplied by each other.  For example:

This 5 and 2 are multiplied by each other to make 10.

I did this all the way up the pyramid until I got to the number 192,756,122,160.  Also known as one hundred and ninety two billion, seven hundred and fifty six million, one hundred twenty two thousand and one hundred and sixty.

Word Problems 1

WALT: Applying my knowledge to word problems. 

This week in maths, we learnt about word problems. We learnt how to figure out if the word problem was to be solved with... addition, subtraction, multiplication or division. The five steps to solve a word problem...

1. Read

2. Underline important information

3. Select a strategy 

4. Solve

5. Check

I have learnt lots from this and hope to remember this for the future.

Multiplication and Division- Week 2

WALT: Solve story problems using only multiplication and division strategies.

In week two we used a lot of algorithms and I was challenge. This post was very late but I still remember how I struggled with this presentation. I am fine with working with a algorithm but I did struggle. Here is an example for a problem and solution:

532

x 23

1596

10640

12236

I have learnt that if the bottom number has a number in the tens unit, it will always start with a zero. Just like the zero made bold. I think that the presentations after week 2 were much better with the solving.

Thinkboard - 2

WALT: Express remainders as decimals.

This took me a while to figure out so here it is and hope you can see it. Seini (my friend) helped me and we marked each others work. There will be more of these think boards and I hope I will keep up with my work.
