Example: Felix made 12 butterfly buns and iced them. He placed two chocolate buttons on top of each bun. How many chocolate buttons did he use?


Patterns


ƒ This strategy involves pupils investigating how numbers, images or symbols are arranged in a variety of orders.


ƒ Each pattern follows a rule. Pupils may be asked to identify the rule in a pattern, find the missing value(s) or extend the existing pattern. Many things in our world follow a set of rules, so that we know what to expect.


Example: Millie is making a beaded necklace that follows a pattern of red, green, blue. If she uses 18 beads in total, how many red beads will she use?


Make a table


ƒ When puzzles are written in word sentences, they can be confusing for pupils.


ƒ Making a table helps pupils to organise the information that they have and identify the information that they need.


Example: Mikey saves €4 on Monday. Each day after that, he saves twice as much as the day before. How much money will he have saved by Friday?


Act it out


ƒ Acting it out is an effective strategy for pupils who have difficulty visualising a problem. ƒ Acting out a problem using props such as cubes or string, or in pairs or groups can greatly simplify finding solutions and is an effective strategy for demonstration purposes in front of the whole class.


Example: I have a 5 litre jug and a 3 litre jug. How can I measure out 7 litres of juice using these jugs?


Make a model


ƒ By making a model, the pupils are given an opportunity to showcase their understanding of a specific area of maths. For example, pupils can investigate the properties of 3-D shapes through model building.


Example: Using 26 cocktail sticks and Blu-tack, how many cubes can Emily make and how many cocktail sticks will be left over?


Simplify There are three ways in which pupils can simplify a puzzle:


ƒ Reword the puzzle using a more familiar setting. ƒ Break the puzzle down into steps and solve one part at a time. ƒ Use smaller numbers.


Example: Amy spent of her savings on a new jacket. If she had €320 in savings, how much


did the jacket cost? 1 8 of €32 = €4  1


8 of €320 = €40 1


8 7
