Bottle Top Bugs – What do you notice?


Digit Dog and Calculating Cat have arranged their bugs in 4 rows of 4.

What do you notice?

How many ways can you finish the sentence?

I notice that……….

Is Calculating Cat correct? Or has she made a mistake? Convince me. Explain your thinking.

What can you say about:

  • the rows?
  • the columns?
  • the number of bugs?
  • patterns in the numbers on the bugs’ backs?
  • diagonal patterns?
  • odd ones out?
  • totals of spots?
  • their eyes?
  • anything else?

Digit Dog is also asking What do you wonder?

Look at the bugs and finish the sentence – I wonder…………..

How many ways can you finish the sentence? You might say things like:

I wonder what the total of each row is……

I wonder which row has the lowest total……..

I wonder if I can arrnage the bugs in order………

Collect the I wonder statements to use as challenges and activities.

What’s the same and what is different about the pairs of bugs?

What has Calculating Cat noticed about the spots?

What patterns can you see?

Look at each pair: which bug has more spots? which bug has fewer spots? How many spots do they have altogether?

What if you were making 6 spots with just one bug? What patterns would you see then?

What if you made other numbers of spots?
