Our grade fives have been working on the subtraction of four digit numbers using regrouping. They have also been working on parts and totals. After our unit on addition and subtraction of large numbers, we will be going on to tackle even larger numbers! Look out, one million - here we come!

| How much is that ransom, again? |
Our grade four students have been working on using different multiplication strategies such as arrays, multiples of ten, and doubling. Using doubling, we have begun to look at multiplying a two digit number by a one digit number. Formal equations are next!
 |
| Mary Kate and Ashley are experts in using doubles. |
Our grade threes have been working on adding different sums (including money) using regrouping. They have been working with base ten blocks to really solidify the concept. Next they will be moving on to using the power of regrouping for subtraction with two and three digit numbers.

| Base Ten blocks make learning concrete. |
Our grade one contingent is deep into a unit on measurement. After a study of length and width, we've moved on to look at mass. We've been having a lot of fun using our scales to compare different objects. The scales have also been handy to look at different units of measurement when considering the mass of an object. It takes 43 paperclips to balance out an eraser.

| We used a scale like this one to experiment with mass! |
That's all for this week's math update. We'll try to catch up at the same time next week!
