Counting down

At one of the year-end parties lately, I was asked if I’ve enrolled B in any math or english enrichment classes, now that he’s starting kindergarten? Honestly, I was a bit surprised and then had a little kiasu moment! I started thinking: What head start are other local school-going kids getting?  How can B grow to love and excel in math and science? Will he face stiff pressure in a country where students have come out tops in the TIMSS international math and science assessment for years now?

Well, I don’t have all the answers to my questions but I do know that since he was a wee baby, math was part of our daily talk and B enjoys books, art and activities like puzzles that involve math. He’s developed decent number sense, ability to sort, compare magnitude, and sequence patterns.  He’s getting better at (re)constructing, and spatial awareness in describing, acting, drawing or writing out locations and directions. He’s also building familiarity with number bonds through DIY manipulatives and games like our recent ping pong ball roll, as well as reading and writing numerals and numbers in English and Chinese.

We “talk math” all the time, be it tracking the dump trucks we pass along the highway, counting the number of kids that need high chairs, figuring out the change from the drink stall aunty, identifying patterns in modern art when we visit museums, guesstimating how many gingerbread men can be cut from the rolled dough and how many baking trays are needed. He’s also getting exposed to decimals when I time how fast he can wear his own clothes, fractions after reading the The Gingerbread Man book and eating away parts of his own cookie …

Most recently, B is also learning how to tell time (analog, not digital), nicely reinforced in Chinese by Sparkanauts too!

Perhaps Singapore math requires much more than what we’ve done so far, and maybe B might have received a more structured approach in a Montessori school, but I’m glad we’ve laid some basics in place in an organic, hands-on way. To quote Mark Twain, “The secret of getting ahead is getting started.”  How have you helped your pre-schooler and primary going kid in math?

Rockin’ and rolling with math

We’ve spent more weekends indoors than we’d like lately, but the good thing is, B has had more time to play his cars, trucks and trains, draw and write, practice violin, of course, craft with mom.

The DIY ping pong ball runs with toilet paper rolls has been a regular activity at home.  But this year, inspired by a fellow mom blogger, I decided to use this to reinforce addition.  Here’s how we did it:

  1. Start storing your rolls!  Even with a 5 person household (+ grandparents!), we could only do enough for numbers 1-5 to start.
  2. Find a board that’s big and sturdy enough, preferably as tall as the kid and sufficiently wide so that you can do a lot of creative (and long) runs.  We used our TV box – as we’d just upgraded our ancient flat screen TV in time for our SG50 NDP party.
  3. Cut some into half lengthwise, and a few others into half heightwise.  The longer halves will be used for the ramps while the shorter rolls as your numbered “holders” or entry points.
  4. Get the kiddo to help you paint the box and rolls.  We didn’t have much time, and B was eager to get rolling, so we just painted 10 short rolls and numbered them from 1 to 10.  He could do all of this by himself now – another plus!

  5. Start sticking them onto the box, testing the roll as you go along.  By now, B could also figure out where to put things and we had fun cutting out the tape and placing them together.

  6. On a separate paper / nearby easel, put together the sums for them to do.  We started from the basics, i.e. 1+1= ? to 1+5 =?, which B already knew from finger counting, so he could draw the connection from adding the balls.
  7. Start rolling based on the sums that you see, e.g. for 1+3, put 1 ball in the #1 holder, and 3 balls in the #3 holder, check how many balls land in the box to see if you got the sums right!
  8. Get the kiddo to write the answer down.  Good practice here 🙂
