Word Problems - Week 5.

WALT: Use 2 different strategies to solve word problems.


During this week we've also been learning about Word problems, a few in our class tend to get confused as they're focusing on the words more than the problem. Today we have a few word problems today, take a look in the presentation above to see what I've been working on.

Test Practice - Week 3.

WALT: Practice before the real test.

Maths - Word Problems!

WALT: Find an appropriate strategy to solve each word problem.


We've started this term up with Word problems, We had to answer decimals and fractions. Here's my presentation above, Take a look with what I've learnt this week.

Understanding negative numbers!

WALT: understand negative numbers.

Throughout week 5-6 we've been learning about Negative numbers and how they're different to positive numbers. We learnt how to subtract and add with negative and positive numbers, The number line of it and how this could be use in different things around our lives.

Negative Numbers!

WALT: Understand negative numbers.
 

Throughout week 5-6 we've been learning about negative and how to add/subtract these numbers, I've learnt the differences between positive numbers and negative. That positive numbers are above zero and the negative numbers are below zero.

Week 1&2: Geometry Words. Directions.

WALT: Use Geometry words involving directions.

These two weeks of school, During maths we learnt how to use geometry words involving directions. We had to use one of our street maps and locate 3-4 other locations of how to get there using Geometry words. Such as: North, East, South and West or Never Eat Soggy Weet bix. (My way of remembering it.)

Week 1&2: Decimals.

WALT:
- Add tenths and hundredths.
-  Use geometric language.


Throughout the two weeks of school, We learnt about decimals. How we could add tenths and hundredths, We also used fractions to compare with decimals. Our class learnt how to use word problems, For an example: Sixty two and five tenths.

Extension Work - Maths

See if you can solve these word problems. Show how you worked it out!! (use brackets to expand numbers)

1. It rained 1.35 inches on Saturday and 1.98 inches on Sunday. How much did it rain on Saturday and Sunday combined?

• 1.35 + 1.98 = 3.33
• (1 + 1 = 2)
• (0.3 + 0.9= 1.2)
• (.5 + .8 = 1.3)

2. There were 7.6 litres of water in Jacob's bathtub. Then 2.9 litres drained out. How much water is left in the bathtub?

• 7.6 - 2.9 = 4.7
• (7 - 2 = 5 )
• ( .6 - .9 = .3)

3. A carpenter bought a piece of wood that was 6.15 meters long. Then he sawed 2.14 meters off the end. How long is the piece of wood now?

Statistics - Maths

WALT -  Identify and uses tenths to make numbers

This weeks task was Statistics, We had to Identify the uses of tenths to make numbers. We used graphs, Percentages, Decimals and Fractions. I learnt that I do over think about the question instead of just thinking of the main topic, We learnt about the interpret and a range of graphs. Different graphs have different uses to them.

Recognize Tenths

WALT -  Identify and uses tenths to make numbers

This weeks task was to focus and identify the uses of tenths to make numbers, We compared fractions and decimals and how we could change one to the other. Our class was handed a presentation with 19 slides, We had two weeks to finish this task. We learnt the place value of decimals and fractions and whats the value of it.

Popsicle Decimals.

WALT -  Identify and uses tenths to make numbers


This weeks task was to identify and use tenths to make numbers. We used Popsicle sticks to round up the numbers we were given, We then added both decimals to get the result we wanted. To get the right answer we used Popsicle sticks.

Well Weathered - Maths

Answer:

• Kaitaia at the moment is the best weather out of Kaitaia and Tekapo, As it shows in the graphs Kaitaia is just above Tekapo in weather

• In Kaitaia and Tekapo the weather is great the sun is out but it’s just way too cold. Even though its sunny it can be cold.

• How much it went from the start to the end, It could show us what temperature it was at the start and how cold it was at the end of the night.

• Yes, As it shows in the graph Kaitaia was the warmest.

• Tekapo seems to be the one that rains less than Kaitaia, Kaitaia weather hasn’t been all sunshine.
• It starts off with a low amount of rain and than it goes heavy rain.
• I wonder how long did it rain for?
• I discussed with my class mate that it may of rained all day since the levels of the rainfall is very high but then we also think that it may of rained in the morning, afternoon than at night.

Too Much Telly

Answer below:

1:

• They spend more time watching Tv

2:

• It's different because the time changes every day throughout the week

3:

• Yes because they’ve spent more time watching Tv then doing their homework unless in that small amount of time they finished and it was easy from their perspective.

Answer questions below:

1:

• Same: They both spend more time watching tv then doing the homework.
• Different:Room 5 spends more time doing their homework than Room 6.

2:

• Yes, Did you know that it could wreck your eyesight. It also disturbs your brain, Sleeping patterns and you’ll forget to do things you’re meant to do.

3:

• They spend more time watching Tv or either doing something other than Home Work, What I think we need to do is to at least spend 10 - 20 minutes answering 5 - 10 questions.
