Preparing your child for school: Sorting and Classifying Objects

Matching and Sorting/Classifying are likely to be the first maths activities that your child will explore in Junior Infants. I have to say that I love exploring Classifying. Its so much fun to see how kids will “sort” things out. I love giving them a “mystery box” a.k.a the contents of “the junk drawer” that never gets fully tidied. You know it, its the one with all sort of bits and pieces in it. Buttons, magnets, bits of lego, McDonalds Happy Meal gifts… The all sorts of everything drawer.

I would like to introduce you to some very dear friends of mine:

Meet the Venn Diagram:

It’s basically a circle. You can classify objects with your Venn Diagram in lots of different ways:

Sort by Colour: Here is a set of yellow bears:

Now meet the Carroll Diagram. You can sort and classify objects in the same way that you did with your Venn Diagram. It’s a matter of preference as to which form of diagram you use.

These diagrams just as to help your child to organise his/her thought. I am sure that you all have lots and lots of bits and pieces that can be sorted and classified. If you would like to purchase some “counters” or “manipulatives” to use during the year then check out this link. I just LOVE Prim-Ed’s manipulatives. At a price point of 9,95 Euro,  for 144 plastic pieces, they are quite affordable. The quality of these counters is just fantastic. They are brightly coloured and robust.

I recently got the Vegetable Counters. I have some plastic fruit in my classroom . I think that sorting fruit from vegetables is going to be a nice maths/science lesson. I will be using them in lots of other lessons throughout the year.

I made a set of corn on the cob (my absolute favourite vegetable!!) and then a set of corn and a set of other vegetables.I’m pretty good at classifying, don’t you think?! Image 2

You could add some yellow apples to the corn on the cob and make it a yellow set. Think of the possibilities!!!!

Here are the objectives as laid down by the Department of Education and Science for Junior Infants:

Strand: Early Maths Activities         Unit:  Classifying

  • classify objects on the basis of one attribute, such as colour, shape, texture or size
  • identify the complement of a set (i.e. elements not in a set)

Here are some free sorting mats that I have created for you all to use. Click here to download.

If you have older children then  print out the mats, pop them in polypockets and send them out to the garden on a scavenger hunt. How can they classify their findings? These “early maths activities” are not just “child’s play”. They prepare your child to collect, describe, assess and analysis data. Perhaps you could have a future scientist or engineer on your hands as a result ;)

Have fun sorting and classifying,

Miss Mernagh :)
