Application For Today’s Maths Lesson: Fractions Of A Collection

Use your knowledge of fractions or of division to solve the following problems:

 

Support: Mum buys 24 apples and she will use ¼ of the apples per day.  How many apples will she use per day?

There are 20 lollies in the bag and your family eats ¾ of the bag of lollies. How many lollies did your family eat?  What fraction of the bag is left and how many lollies is this?

 

Reinforce:  Your family wants a packet of Ritz crackers to last for a week. What fraction of the packet will your family eat per day and if the packet contains 210 crackers, how many will be eaten each day?

Dad bought apples on Saturday and ¾ of them were eaten by Tuesday. On Tuesday there were 6 apples left, how many apples did Dad buy on Saturday?

 

Extend:  Forty-five chocolates, which is three- quarter of the box, have been eaten from a 1kg

box of chocolates.  How many chocolates does the 1kg box hold altogether?

A test has a possible score of 80 points and you get 9/10 of it correct.  What score do you get?

The next test has a possible score of 75 and you get 4/5 of it correct.  What score do you get?

How would you explain which test you did better on?

 

Find a partner who solved different problems to you, show one of the problem solutions and explain your thinking.

Today’s Math Work

From yesterday’s lesson continue working on the work you haven’t completed then move onto that in the next level.

Grp 1-regional models-drawing & making  3/4-2/3; 6/8-8/10; 4/5-7/10; 3/4-6/8; what’s the same as/equivalent fractions to these- 2/3? 4/5? 1/2?- what’s the pattern?

If I cut up a piece of wood that is 10 cm in length and I gave 4/10 to my brother and ½ to my friend which person would receive the most? Why?

(You may use a diagram to show your understanding).

 

Pencils come in boxes of 16. If I give 5/16 of one box to my Sarah and ¼ of another to Bob. Which person will receive the larger amount of pencils? Why? You may use a model or diagram to show your understanding.

Now if I give 3/8 of one box to my Sarah and ¼ of another to Bob. Which person will receive the larger amount of pencils? Why? You may use a model or diagram to show your understanding.

 

Grp 2 –difference between N&D group-Jenny breaks her Mars Bar into 8 pieces and eats 6 pieces. Paul breaks his Mars Bar into 5 pieces and eats 3 pieces. Who has the most left over? Explain using fractions

Pieces of wood are 10 cm in length. I gave 4/5 of one to my brother and 2/3 of another to my friend- which person would receive the most? Why?

(You may use a diagram to show your understanding)

Pencils come in boxes of 16. If I give 3/4 of one box to my Sarah and 7/8 of another to Bob. Which person will receive the larger amount of pencils? Why? You may use a model or diagram to show your understanding.

Now if I give 15/16 of one box to my Sarah and 7/8  of another to Bob. Which person will receive the larger amount of pencils? Why? You may use a model or diagram to show your understanding.

Compare these fractions 6/10 and 2/3;  9/11-4/5; 7/8-6/7; 12/14-16/18; 13/14-7/8

 

Grp 3- smaller denominator group-Jenny breaks her Mars Bar into 8 pieces and eats 3 pieces. Paul breaks his Mars Bar into 6 pieces and eats 2 pieces. Who has the most left over? Explain using fractions

Pieces of wood are 10 cm in length. I gave 7/10 of one to my brother and 3/5 of another to my friend- which person would receive the most? Why?

(You may use a diagram to show your understanding).

Pencils come in boxes of 16. If I give 3/4 of one box to my Sarah and 13/16 of another to Bob. Which person will receive the larger amount of pencils? Why? You may use a model or diagram to show your understanding.

Now if I give ¼ of one box to my Sarah and 3/8 of another to Bob. Which person will receive the larger amount of pencils? Why? You may use a model or diagram to show your understanding.

Compare these fractions 6/10 and 2/3;  9/11-4/5; 7/8-6/7; 12/14-16/18; 13/14-7/8

 

Grp 4 bigger numerator group –Jenny breaks her Mars Bar into 8 pieces and eats 5 pieces. Paul breaks his Mars Bar into 6 pieces and eats 4 pieces. Who has the most left over?

Pieces of wood are 10 cm in length. I gave 4/10 of one to my brother and 3/5 of another to my friend- which person would receive the most? Why?

(You may use a diagram to show your understanding).

Pencils come in boxes of 16. If I give 3/4 of one box to my Sarah and 9/16 of another to Bob. Which person will receive the larger amount of pencils? Why? You may use a model or diagram to show your understanding.

Now if I give ¼ of one box to my Sarah and 2/8 of another to Bob. Which person will receive the larger amount of pencils? Why? You may use a model or diagram to show your understanding.

Compare these fractions 6/10 and 2/3;  9/11-4/5; 7/8-6/7; 12/14-16/18; 13/14-7/8

 

Grp 5-extension- Compare these fractions 6/10 and 2/3;  9/11-4/5; 7/8-6/7; 12/14-16/18; 13/14-7/8

I have a 100g bag of jelly snakes. It has 13 snakes in it- I ate 10. Sam has a 100g bag of jelly beans. It has 22 jelly beans and she ate 17. Who ate more weight in jelly lollies? Prove it.

47/55=56/66-true or false? Prove it.  74/80>19/20-true or false? Prove it.  121/470 < 25% true or false? Prove it

The population of Sarajevo is 520 000  2/3 of them have dark hair. 350 000 of them speak more than 1 language. Which is bigger? Prove it.
