Introduction
Welcome to the Wix platform, a technological advanced site for mathematical learning. Over the next few pages we will be exploring the mathematical concepts with explanation and mini-games. Below is a quick overview of the three sequenced lessons,
Lesson 1 - Introduction to Fractions
Lesson 2 - Presenting unit fractions on a numbered line
Lesson 3 - Addition and Subtraction of fractions with the same denominator
Happy Learning! :)
Task
YOU ARE THE CHEF!
This learning task teaches you the best way to bake a cake, which is only delicious when the correct amount of ingredients are used. The ingredients are measured using fractions, you will have a sense of the numerical values of unit fractions and be ready for some simple addition exercise
Hope you enjoy the activity!
Process
Lesson 1 - Unit Fractions
Welcome to Lesson 1! In this lesson, we will be looking at and comparing the values of unit fractions with the nominator "1".
1. First thing first, what are fractions? Let's watch the video below from another chef and find out

Wow! Fractions are amazing tools to divide an object such as pizza into the given equal portions.
2. I am sure all of us love pizzas. Let's try even more experiment about pizza!
Use the link below to play the game "Pizza Party"

3. Let's pause and reflect on the following questions
After this lesson, please reflect on the following questions and write down your answers
Q1 Highlight from the following that is/are NOT unit fraction/s? (There may be more than 1 answer)
Q2 Highlight the fraction with a higher value
Q3 Reflect: what is the pattern between the denominator of the fraction and its value?
When ready, move on to Lesson 2.
Lesson 2 - Comparing the Fractions
Welcome to Lesson 2. In this lesson if time and weather permits, we will go outside to have a hands-on experience of fractions on a number line. Your teacher will draw a 0-1 number line in the outdoor playground and instruct you to stand at a given point representing a given fraction (e.g. "Student A, go to the 1/3 point on the number line!"). Hope you have fun!
When return, have a few goes at the game "Fraction matcher", starting from difficulty level 1. Try to attempt towards as high level as possible.

And think about the following questions:
Q1 On a piece of paper, draw a number line (0-1) and represent the following points: 1/2, 1/3, 1/4, 1/6, 1/8
Q2 Highlight the pair of fractions that are equal

When ready, move on to Lesson 3
Lesson 3 - Addition of Fractions with the same denominator
Welcome to Lesson 3! We have now come to the most exciting part of making the cake. As mentioned in the earlier introductory page, you will have to measure the correct amount of ingredient to make your cake as tasty as possible.
First of all, let's practice with some calculations with the mini game

Now, time for some baking!
Here are the ingredients needed to bake a cup cake:
1 eggs
1/4 cups of sugar
2/3 cups of flour
1 teaspoons of butter
1/4 teaspoons of vanilla flavouring
1/2 cup of water
IMPORTANT: Do your addition calculations carefully! You will use DOUBLE the amount listed above to bake a big cake, using the cups and teaspoons provided.
Feel free to take note on how many cups and teaspoons you need to use to prepare the ingredients. Now, follow these steps
1) separate the egg yolk and white. To the egg yolk, add the above ingredients. The flour should be added in two batches. Stir them well.
2) stir the egg white until foam is formed
3) mix the egg write and yolk together
4) preheat the oven to 180 degrees (C), place the mixture on a baking tray and bake in the oven for 30 minutes. Cool it down and enjoy!
Evaluation
| Are all the tasks are completed? | 1 - no or little attempt to complete the learning tasks | 2 - limited attempt to use learning tasks to build understanding | 3- all tasks are attempted at least | 4- nearly all tasks are attempted and finished | 5 - all tasks are completed with good quality |
| The practice questions showing sufficient level of understanding of mathematical concepts | 1 - no questions attempted or the answer showed no or very limited understanding | 2 - limited understanding demonstrated in the answer | 3 - all questions are answered with some error and limited explanation | 4- all questions are answered with little explanation | 5- nearly all answered are followed with detailed explanation |
| The ability to apply the mathematical knowledge (fraction) across different scenarios | 1 - lack of basic understanding of fractions | 2- very limited understanding of fractions, preventing the ability to apply the knowledge into different scanerios | 3 - being able to think about the mathematical concept when given a reallife situation (e.g. standing on a number line, pizza, cake etc.) | 4 - developing proficiency | 5 - sufficient proficiency and confidence in applying fractions into real life calculations |
