You did a brilliant job yesterday of identifying 'how many altogether' when presented with two groups of objects. We are going to continue to combine two parts to make a whole today using the part-whole model.
Let's first think about what a whole is. Whole is all of something. For example, if I had a whole apple, I would have the entire thing. What is a part? A part is a section or amount of something, of the whole. Take a look at the picture below. It shows a whole apple and two parts of an apple. Ask an adult to play a quick game with you. Your adult is going to say either 'whole' or 'part'. Your task is to point to whichever one they say as fast as you can. For example, they might shout "whole" and you will point to the whole apple. Then they might shout "part", how quickly can you find the part? They might shout "part, part, whole, part, whole", can you keep pointing to the correct one? Don't let them catch you out!
As well as splitting objects into parts from their whole, we can split numbers and amounts into parts too. The part-whole model is the concept of how a whole number can be split into parts. I have seen some of you using these in your work already which is fantastic. Let's keep practising today!
You first task today is to create your very own part-whole model to use (keep your resources somewhere safe as we will use this a lot more over the coming days and weeks). I have made a part-whole model at home, as you can see below. I used paper plates and lollipop sticks to make mine but you can make yours however you wish. You might like to use plates, bowls, hoops, lids from jars or simply a pencil and paper to draw your own.
I have put some objects onto my part-whole model. How many blueberries have I got? How many strawberries have I got? Can you subitise the amounts on each plate? Which plate has more? Which plate has fewer?
I want to know how many pieces of fruit I have got altogether. To do this I can combine the two parts to make a whole, just like you did yesterday when you counted how many objects you had altogether. I am going to move my pieces of fruit from the parts to the whole.
Now I have combined my parts to make a whole, I can count how many pieces of fruit are in the whole. 1, 2, 3, 4, 5, 6, 7 - I have 7 pieces of fruit altogether.
I need your help to finish combining parts to make a whole today. As you can see in the pictures below, I have two parts but I am not sure what the whole is. Can you use your own part-whole model that you have made to work out the whole? Remember, your objects do not need to be the same as mine. I have used fruit but you can use your own objects to represent what is on my model. If you have any questions, please just shout.
If you find the whole to each of these and want to continue practising, ask your adult nicely to place more objects on the parts of your part-whole model. Can you find the whole?
