Product Information

But when I get to my third ten frame, I see one empty space, and we know that nine is less than one, which means we have two full ten frames, which is 20 and nine more, which is 29. Today we are working with 29 balloons and what we need to do is to put the balloons into bunches that have the same number of balloons in each bunch. Now, because we know our total number of balloons and that's 29, but we don't know how many bunches we're going to have yet, and we don't know how many balloons are going to go into each bunch. We're actually using a strategy called trial and error. I think to begin with, I might try bunches of five balloons. What do we think? Let's see. Now, I have four sixes. Oh, but mathematicians what do you notice? I've got one missing, this particular group, it can't be a group of six, it's only a group of five. So, I have four sixes and one group of five. And that means that we can't put our 29 balloons into equal bunches of six. Well, it's over to you mathematicians, now it's your turn to see what numbers you can use to try and make equal bunches using your 29 balloons.

The speaker arranges 4 playdough balls into a bunch. She then arranges another bunch of 4, then another, and then another. She has 2 balloons remaining.] Speaker Choose a disposable helium tank – if you’re planning to inflate many balloons or make balloon decorations, these tanks can be delivered to your door and are easy to operateSo mathematicians, how did you go exploring with your 29 balloons? I asked my friends to do this activity too, and I've got some of their thinking to share with you today.

So this is my friend Bob. Now Bob's thinking, I can see that he was using groups of eight. But just like Tom, Bob also had some left over. And he's put them here in a group of five. Bob had one eight, two eights, three eights, but then he had these five left over. Now I really like how I put tonnes into an array. That helped my brain to see things clearly with his leftovers. Let's use the same strategy again using Bob's thinking over here. Let's start with this eight. colourful playdough balls are arranged in 3 groups over 2 sheets of paper, that have been taped together. 2 of the groups of balls are arranged into 2 rows of 5. The other group of balls is arranged into one row of 5 and one row of 4.] Speaker The NSW Department of Education is committed to employing the best and brightest teachers who can teach and make a difference in NSW public schools. Balloon archways – these are ideal for the entrance to your party, or to decorate the buffet table or the top table at a wedding

Using the orange marker pen, the speaker draws a horizontal line across the piece of paper on the right of screen.] Speaker Next, we tried equal bunches of four, but we discovered that we had two left over, so we knew we couldn't share them equally using fours. The speaker places a third piece of paper, and a purple pen, below the other 2 pieces of paper in front of her.] Speaker So I can draw a line like this and I'm going to record my left over ones underneath. They didn't quite make a group of eight. One, two, three, four and five.
