Problem Solving Friday!!!

Have a go at the following word problems.  Some are easier than others:

 

For challenge 6, think about how many degrees are in a full circle (we know that a straight line is 180 degrees).  The circle is split into 5 sections so how many degrees would each section measure?  I hope this helps you calculate your answer.  Or can you name the type of angle?

Post your work on Seesaw for you teacher to see!

 

We know that a right angle measures 90 degrees and a straight angle measures 180 degrees.

Usually we would use a protractor to measure angles but if we know the angle is a right or straight angle then we can use a calculation to work out the angle size.  Sometimes these angles can be split to create smaller angles.  Here are straight angles split into smaller angles:

Task:

There are 2 chilli challenges for you to complete – Mild and Hot.  Have a go at calculating the angles without using a protractor.  Remember the information above to help you with your calculations.

Good Luck!

Angles  Mild  Challenge

Angles Hot Challenge

 

 

 

An angle is a measure of how one line is rotated onto another line (where the 2 lines join).  Angles are measured in degrees.  There are various names to describe angles, based on their sizes:

The curved/circular line in the angle examples show the size of the angle.  Sometimes a right angle is represented with a square rather than a curve.

Can you identify what the following examples are using the correct names:

acute, right, obtuse, straight or reflex

Venn Diagrams

Venn Diagrams are a way to display information.

Under apples there is information only  relevant to apples.

Under oranges there is information only relevant to oranges.

In the middle section, where both circles cross there is information relevant to both.

 

Pick two different fruits and try to make a Venn diagram of your own !

Today you are learning about coins and the values of money.

You will need a selection of coins.

• Can you put the coins in order from lowest to highest value?
• Can you put the coins in order from biggest size to smallest size?

Task 1

• How many 1p coins would you need to make £1?
• How many 2p coins would you need to make £1?
• How many 5p coins would you need to make £1?
• How many 10p coins would you need to make £1?
• How many 20p coins would you need to make £1?
• How many 50p coins would you need to make £1?

Task 2

Look out the coins you would need to make these values:

• £3.47
• £2.33
• £1.97
• £4.00
• £4.53
• £0.32
• £0.46
• £3.33
• £2.87
• £1.98

Task 3

If I went to the shop and used a £5 note to pay, what change would you get from these items?

• A carton of milk at £1.20
• A packet of crisps for £0.65
• A packet of apples at £1.23
• A cereal bar at £0.57
• An Easter Egg at £3.99

Today we are going to be continuing to work of addition.

Lets start with a number talk.

38 + 23 = 

Try using compensating to solve this calculation.

Today we have set a Sumdog challenge!

You are going to be working on your addition skills and there are plenty of coins up for grabs.

Number talk

How many different ways can you solve the caluculation : 17 + 8 = 

Try using

• partitioning
• compensating
• making tens

Today we are going to be looking at addition! Head to MathsBot.com for today’s activity.  https://mathsbot.com/manipulatives/blocks

Use the Dienes materials to answer the following addition calculations.

1. 43 + 19 =
2. 26 + 15 =
3. 21 + 11 =
4. 78 + 34 =
5. 83 + 23 =
6. 145 + 27 =
7. 183 + 201 =
8. 230 + 111 =
9. 249 + 250 =
10. 493 + 121 =

When you are finished :

• Make 10 new calculations to challenge yourself
• Use Sumdog for 10 minutes to work on your addition skills
• Play Jack, Queen & King. Use playing cards to try more complex addition.
