Odds and Evens

Introduction

Hello year 4!

Our new topic for Mathematics is...

Odds and Evens! over the next few lessons we will aim to understand the rule in odd and even in addition, subtraction, multiplication and division. 

So what is the rule? Let's get into it and find out. 

AC9M4N02 Explain and use the properties of odd and even numbers.

Task

Lesson 1

Task 1: 

Introduction of odd and evens!

We are going to create bingo cards! so we can play odd and even bingo in the classroom.

To do this we need to understand what an odd number is and what an even number is. If you are still stuck on odd and even numbers have a look at the chart to help guide you.

Task 2:

 

Play bingo with your peers, swap cards with each other. 

 

Task 3:

 

Come up with your own game that can challenge you with odd and even numbers. 

 

Lesson 2

Task 1:



Addition in odds and evens! 



This task requires you to understand odd and evens in additions. What will you get when you add two even number together? Let's get our minds to work. Let's work out the rule for addition in odd and evens. 

What numbers do you need to add up to 10? Are they all odd? are you all evens? Or are they both? this is what you will work out 



What numbers together make up 15? Are they all odd? are you all evens? Or are they both? this is what you will work out.



What numbers together make up 33? Are they all odd? are you all evens? Or are they both? this is what you will work out. 

Task 2:

What will be helpful for you when learning odd and evens? let's make a helpful tool to look at for when we need some help.

Lesson 3

Task 1:



Odd and evens in Multiplications!



Our first task is to work out if our rule for addition is the same for multiplication. How will we do this? 

Todays lesson activity is called roll of dice. 

Roll of dice is an activity to create understanding of the rule and seeing if it matches the rule of addition.

Task 2:

working in your group to create a rule poster to help you as a tool to look back on if you need help to remember what the rule is and how we can work it out. 

Lesson 4

Task 1:



We are going to make our own snakes and ladders game!

Everyone will be making their own board game and we are going to swap with our peers. 

Process

Lesson 1

Step 1:

Create a table 3 rows and 3 columns. 

Step 2:

Using numbers 1-100 place numbers on the chart using both odd and evens. 

Step 3:

Use the counters labelled even and odd and with the use of a number generator. Click the generator to get a number if your number is on the card place a counter on the number labelling whether it is even or odd.

Task 2:

Once you have finished return to the floor waiting for another 3-4 peers to join you and you will all play bingo using each others cards. play each peer's card at least once you can continue playing or you can move onto task 3 as task 3 is optional.

Task 3:

Come up with your own game that can challenge you with odd and even numbers. 

Lesson 2

Task 1:

We know what numbers make up the number 10

I want you to work out what you need to make the number 10 odds or evens? one of each? or both?

Step 1: Write down each addition sequence.

Step 2: Label Odd or Evens or both. 

Step 3: Once you have worked those out and written whether they are odd or even we will move onto the number 15 what numbers we can add together to make 15?

Step 4: then work out if they are odd or even. 

Repeat these steps for number 33 and if you haven't worked out the rule choose another number and complete steps again. 

Repeat this process until you think you have worked out the rule for addition. 

Task 2:

Once you have the rule and are finished early I want you to think of how you can make an odd or even chart for yourself and design your own helpful chart for odd and evens and begin to create that chart. 

Lesson 3

Task 1:

In table groups of 2-3 peers.

Step 1: do you think the rule is the same? 

Well we are going to find out. Today's lesson you will either use the dice app or require two dice.

Step 2: Roll 2 dice. or press the dice twice to get 2 numbers. 

Step 3: Write or type the number you get.

Step 4: Identify are these both odd or even or are they one of each?

Step 5: Multiple the two numbers together. what do you get? 

When you have worked out at least 10 multiplications written and think you know the rule one student from the group bring the working out with the rule to the teacher. 

 

Task 2: 

Once your group has the correct rule your group will create a rule poster either using the Ipad or computer. Work together to make it easy for us to read and see as we will be putting this in our room as a guide. 

Lesson 4

All of you have an empty template for a snake and ladder game. 

Step 1: for each box there will be an equation for you to come up with using addition or subtraction. make sure you know if the answers are even or odd numbers as this is important for the snake or ladder squares. 

Step 2: ladder squares - you must choose is this going to be an odd answer OR even answers it can NOT be both because if you choose one the snake squares will need to be the opposite. 

Step 3: Once you have completed your game have a look over for mistakes and fix them if there is. Once you think you are done bring your board and a dice to the mat on the floor. the first student finished after you is now your new partner and you will swap boards and play the others card. 

Step 4: If you have completed your board and played another peers game collect another board and follow the steps again but this time using multiplication and division. 

 

Evaluation
Conclusion

What the students are being required to do here is become competent in odd and even numbers, how we use them in addition, subtraction, division and multiplication. These activities are hands on activity for engagement, use of electronic's to complete tasks such as the use of dice, using ipad or computer to assist the students learning. Student focused activities to encourage the students to scope their own games and create a way to help them work out the answers. The activities have been adjusted to fit in with the age group, topic and the activities have follow ons for those students who may be more advanced but still allowing each student to be able to participate with their ability.
