Welcome back to our class blog. These weeks just seem to be flying by.

In English this week, we have been looking at an amazing book -one that has really inspired and fired our imagination. `The Day the Crayons Quit’ is a book written by Drew Daywalt and illustrated by Oliver Jeffers. It is the story of a boy, Duncan, who one day finds a pile of letters addressed to him. These letters have been sent to him by his crayons. They are writing to him for a number of reasons -Yellow and Orange Crayons are arguing over the real colour of the sun -the Red Crayon feels over worked -and Beige Crayon wants to be known as Beige, not light brown or tan. On Thursday, we imagined that we were a crayon writing to Duncan. We thought about what other colours might be in his crayon box, then why they might need to write to him.

Take a look at our writing.

In Maths, we have been adding and subtracting fractions. Yes! Adding and subtracting fractions! Amazing eh? Actually, they’re really quite easy. When adding or subtracting fractions, add or subtract the numerator (the top number), leave the bottom number the same.

So that,

2 + 2 = 4 (2 add 2 equals 4)

5 5 5 (this number stays the same)

We’ve also been having a little challenge online with these adding and subtracting fractions game. Our current record is Evie with 17 correct out of 17 in one minute. Check them out (adding) here and (subtracting) here.

Here's our latest favourite game -Fling the Teacher.  Check it out here.

If you dropped in last week, you will remember we set up a Science experiment. We placed eggshell in to 5 different liquids to see how each would react. Eggshells and teeth both contain large amounts of calcium. The outside of an eggshell is much like the enamel of our teeth. So, this experiment would show the amount how different amounts of sugar in drinks could affect our teeth. Take a look at our results.

Amazingly, though we did predict it based on the amount of sugar (though it is natural sugars), the fresh orange juice appeared to cause most damage.  This shows just how important it is for us to brush our teeth at least twice a day.

Glad you could make it again this week, hope you can pop back next week... for the continuing story of Year 4.
