POEM PRACTICE
We practiced our poems for Music festival and then silent read.

MATH
We discussed how arrays can help in multiplication.

For example:

X X X X
X X X X
X X X X

This array has 3 rows of 4 items. The corresponding multiplication sentence would be:

3 x 4 = 12 or the repeated addition sentence would be 4 + 4 + 4 = 12

* Arrays always need to be written with the number of rows first and the number of items in each row second.

A story problem for the above array might be:

There are three dogs. Each dog has four legs. How many dog's legs are there altogether?

ASSEMBLY
We had our second assembly this week and the grade three students did a wonderful job of reciting their poems. The grade three students in the grade 3-6 Choir also sang "Imagine" and "My Favourite Things". We also got to hear the K-2 Choir sing two songs, and the grade five and six classes did their poem recitations.

SCIENCE
We watched a BrainPop on States of Matter. It discussed how the boiling point at which liquid turns to a gas is also called the point of vaporization. The melting point where a solid turns to a liquid is called the point of fusion. In a gas the molecules are spread out and randomly bounce around. In a liquid the molecules clump together and move more slowly. In a solid the molecules form a lattice structure, similar to an array, and move so slowly that they only vibrate. Some solids change directly to gases, which is called sublimation. An example of the this is solid carbon-dioxide or dry ice, which changes directly into a misty vapour with no liquid state.

SHOW & SHARE
We heard that the Easter Bunny brought lots of chocolate to the grade three students most of which has already been eaten. Other Easter treasures included keychains, a RoughRider baseball cap, and a special set of hockey nets and sticks.

Remember the playground is still quite wet and rubber boots and splash pants are a good idea for recess times.
