Maths mate sheet 6 term 1 question 22

predict: I predict that this is going to involve problem solving.

read: draw the missing house.

clarify: —

big question: what is the missing house?

solve: I looked through the whole picture and saw which parts of the house there were only 2 of. I knew I had to look for pictures with 2 because i knew that the ones with 3 are already done.

mathematicians toolbox strategy: I used guess check and improve and have I seen  this problem before.

Maths mate sheet 6 term 4 question 22

Predict: Addition, Subtraction and prior knowledge.

Read: Move one match to make this statement correct.

clarify:–

Big question: Move a match to for fill this question.

  • Do I know a similar problem
  • Guess, check and improve
  • Try a simpler problem
  • Write an equation
  • Make a list or table
  • Work backwards
  • Act it out
  • Draw a picture or graph
  • Make a model
  • Look for a pattern
  • Try all possibilities
  • Seek an exception
  • Break the problem into smaller parts

Solve: First we took a match of the v and then replaced it with a match from the answer and we completed our question. the v then looked like this….

Read; Move two matches to leave four squares.

clarify;

big question; what two matches will i have to move to get four squares.

Solve:I took of the two end matches. The end left and the end right match to get 4 squares.

Bar graphs

Description 

This term our class is studying Forensic Science. As part of that we all had to take tally of the class and some given traits. After we had collected our data we then decided to put it in  to a graph of our choice. We choose a Line graph. Look below for image.

Mode:

Mean:

Median:

Average:

We then had to make a procedural text on how to make a bar/column graph.

 

 

Maths Mate Sheet 4 question 23

Predict:I predict this is going to involve multiplication and subtraction

Read: I think of a number double it and then add 8 .If  I end up with forty what was my original number?

Clarify:

Solve: so first i took 8 away from forty which equaled 32. Then halved 32 and got 16.

Answer: 16

Maths Mate Sheet 3 Term 4 Question 23

Predict: I predict this is going to involve the four operations.

Read: I think of a number, double it and then add 4. If the result is 20 what was the original number?

Clarify: —-

Big Question: What was the original number?

Mathematicians toolbox: 

Your mathematician’s strategy toolbox includes:

  • Do I know a similar problem?
  • Guess, check and improve
  • Try a simpler problem
  • Write an equation
  • Make a list or table
  • Work backwards
  • Act it out
  • Draw a picture or graph
  • Make a model
  • Look for a pattern
  • Try all possibilities
  • Seek an exception
  • Break the problem into smaller parts

Solve: Well first I read the question. Then I started with 20, subtracted 4 and ended up with 16. Then I used my prior knowledge to know that half of 16 is 8. So as it said” Double 16″ I subtracted 8 and got my original number 8.
Answer: 8

Maths Mate sheet 2 term 4 question 23

Predict: I predict that this problem is going to involve the four operation’s and prior knowledge.

Read: I think of a number, add nine and then multiply by three. If the result was thirty what was my original  number?

Clarify: Nothing to clarify.

The Big question: If I start with a certain number add nine and multiply it by three what do number do I end up with?

Solve: First I read the question really thoroughly and made sure that I understood everything. Once I had done that I chose a number that I thought would be n easy start so I chose one. Then I added nine and I got ten. Once I had done that I multiplied  ten by three and got thirty.

Answer: One

 

5 Cent Frenzy Infograph

Infographs

Q: What is an infographic?

A: A visual image of data.

As a part of our 5C frenzy work we created infographs to create interesting and colourful ways to present our data. There are many online sites the let you create these graphs we used infogr.am

Some of the problems we encountered along the way were

The infogram we chose wasn’t a good one for presenting our information.

What we did to over come these were

Use a different graph.

What worked with our infographs was

It clearly showed what years had the most amount of coins.

What I can improve upon is

Getting quicker at writing in the data.

Below are my graphs

Maths Mate sheet 7 Term 3 Question 22

Predict:

I predict this is going to involve subtraction.

Read:

Jim and his younger sister Rachael were born on the same day of the year, but five years apart. There was a total of 25 candles on their last cakes last birthday how old is rachael?

Solve:

My answer was 11 because i knew that they were  5 years apart so 11 plus 14 =25.

Answer:

25.

Mathematicians toolbox:

I used one of the four operations and that was subtraction.

 

 

Different types of graphs

In our class we learnt about different types of graphs. We have learnt that bar graphs and pie graphs are two of the most simple graphs to read without being to easy. Bar graphs can show you the exact amount of something by the numbers but pie graphs can’t do that because they don’t have numbers they just have colours. So if one colour was twenty people and one colour was nineteen people you wouldn’t be able to figure out which one was bigger and which one was smaller. In conclusion I fell bar graphs are more convenient than pie graphs because they are more accurate.

PIE GRAPH

What Is The Best Way To Loose Weight?

Strengths: It is good to help you learn fractions. Not many words involved mainly colours. Shows how to divide categories.

Weaknesses: It can be complicated to read. Bad if you’re learning to read words. It doesn’t show any numbers to tell you the exact amount.

BAR GRAPH

What is the best sport for your body.

Strengths: Not complicated to understand. Bar graphs are very accurate.

Weaknesses: Bar graphs cant show the number of people that were questioned. Sometimes bar graphs only go up to a certain amount of numbers and if you have more than the number that is the highest on the graph you have to shrink the real answer.
