Linking Lollies

The Ministry is migrating nzmaths content to Tāhurangi.           
Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz). 
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024. 
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

Activity

In this activity, the students need to recognise a pattern and then use fractions to describe the pattern.
Some students may need to use multilink cubes, counters, or diagrams to help them identify the pattern, for example, LOOOLOOOLO …, with L representing a lime lolly and O representing an orange lolly. A table such as the one below may also help.

table.
By completing the first part of the table, the students should realise that the number of lime lollies is the same as the number of patterns, the number of orange lollies matches the answers to the three times table, the total number of lollies matches the four times table, and so on. Once they have made these connections, the students can consider short cuts or quicker, more efficient ways of working. You could encourage them with comments such as “ Do you need to draw a diagram for the next one, or can you figure it out?” From the table, they can see that one out of every four (that is, 1/4) of the lollies are lime and three out of every four (that is, 3/4) of the lollies are orange. Students who have trouble finding one-quarter of 36 need help seeing
the connections between 36 divided by 4, 1/4 of 36, sharing 36 into four equal groups, and 4 x= 36.
At the end of the lesson, have the students share and discuss their methods of working. Students generally benefit from explaining their own methods and listening to other students explain theirs. You could set follow-up activities so that the students could try out the other methods. They could then discuss which is the most efficient method for them.
Other ways of extending this activity could include:
• developing more ula for the students to work out
• having the students develop an ula for their classmates to work out
• asking the students “What if …” questions, such as:
“What if the same pattern were used for an ula twice as long: how many lollies of each flavour would you need?”
“What if the ula were 100 lollies long?”
“What if there were 60 lime lollies: how many orange lollies would you need?”
“What if the same number of each type of lolly were used: what other patterns could you make?”


Answers to Activity

a. Each set of four has one lime and three orange.
1/4 of 36 is 9, so she uses nine lime.
3/4 of 36 is 27, so she uses 27 orange.
b. Each set of five has two raspberry and three blueberry.
2/5 of 60 is 24, so she uses 24 raspberry.
3/5 of 60 is 36, so she uses 36 blueberry.
c. Each set of three has two blueberry and one orange.
2/3 of 24 is 16, so she uses 16 blueberry.
1/3 of 24 is 8, so she uses eight orange.
d. Each set of six has three lime, one raspberry, and two blueberry.
3/6 of 72 = 1/2 of 72, which is 36, so she uses 36 lime.
1/6 of 72 is 12, so she uses 12 raspberry.
2/6 of 72 = 1/3 of 72, which is 24, so she uses 24 blueberry.
