Math
Today we talked about how to use a known multiplication fact (usually an easier one), to find a more difficult fact.
For example if you know 5 x 8 = 40, then 6 x 8 = 40 + 8 = 48.
5 groups of 8 is 40 so 6 groups of 8 is another 8 so it would be 40.

If you find it difficult, draw an array. It helps you figure out what to add or subtract. Eventually, you should be able to reason the product in your head. This strategy also works for doubles. If you know your 4 times table, you can get your 8 times table by doubling. Similarly, if you know your 3 times table, your six times table is just double the 3 times table.

4 x 9 = 36 so 8 x 9 = 36 + 36 = 72
3 x 8 = 24 so 6 x 8 = 24 = 24 = 48

Grade 5 we will use the same reasoning skills to determine more difficult products.

Science
We talked a bit about CHANGES OF STATE. The key ideas:
To change from one state to another state, you must either add heat or take heat away.

Which changes of state to you need to add heat? Which to take heat away?
There are two changes of state in the diagram above we did not talk about today. Which ones?
