News from the 3/4 Team...
Fractions, Decimals and Percentages!
It’s been a fun-filled start to Maths for the term, with Year 3 and 4 students focussing on Fractions, Decimals and Percentages.
Students have played warm up games and participated in open-ended activities and targeted mini-groups, aimed at engaging all students at their point of need.
Through exploration, students have been learning:
- that fractions are even parts of a whole, created through sharing or dividing
- how to recognise and interpret common uses of halves and quarters of shapes and collections
- how to model and represent unit fractions including 1/2, 1/4, 1/3, 1/5 and their multiples to a complete whole
- that percentages and decimals are other forms of fractions
Fraction Name Challenge
Using fractions, can you represent your name using the following criteria?
- How many letters are in your first and last name?
- How many of your letters are vowels and consonants?
- Are any letters repeated? How does this impact the fractions?
Here is Abby's!
Try the activity for yourself.
You could even use other words, phrases or sentences... perhaps a book, movie or game title?
What other criteria can you come up with?
Making a Whole
Using a Fraction Wall, students explored the concept of equivalence and identified ways to add fractions to a complete whole.
Yuvaan, Elias and Baron did a great job!
Fractions, Decimals and Percentages
Students were asked to draw a number line from 0 to 1, then place in position the following points:
1/4, 1/2, 3/4, 25%, 50%, 75%
Around the outside of the poster, they drew and labelled images that could be broken into those fractions, such as a half full bottle of drink, 75% of a pizza, an iPad battery charged to 25%, a bar chart with 16 walkers and 8 drivers, 3/4 of a bar of chocolate.
Using their poster as a reference, students posed and discussed questions such as:
What is the relationship between 0.25 and 1/4?
Is 40% less than, more than or the same as 1/2?
How much greater is 0.75 than 1/4?
Is 91% greater than 3/4? How can you prove this?
Which is greater, 25% or 1/6?
Well done to Ava, Claudia and Peter!
Fraction Flags
Using a grid of 24 squares, students were asked to create flag designs according to the following criteria:
1/4 must be yellow
1/3 must be red
1/8 must be green
1/12 must be black
1/6 must be blue
1/24 a colour of your choice
Here are some of 3AT students' designs!
Can you convert the fractions to decimals and/or percentages?
For those who are interested, here’s a link to a card game that you can play at home:
Half, More or Less - Love Maths
It’s a simple game that helps develop understanding of relative size of fractions. The only equipment you need in order to play the game is a deck of cards!
Looking forward to more Fractions, Decimals and Percentages activities over the next couple of weeks.
