We’ve been busy in grade 4 lately and have lots of work to show for it.
Here are some of our Dodecahedron book reports. They look marvelous! This was a really fun project and I think most of the class really enjoyed it.
Yesterday we played Scoot which is a fast moving game using task cards. These task cards involve spelling words with the “tricky y” rule, what to do when you have to add a suffix like -ing, -ee, – est, -ful, -ness to a root word. Each desk has a task card and each student has an answer sheet where they write the word. When I say “Scoot” they move to the next desk, play continues until each student has finished each task card.
Here is a completed answer sheet.
In math we are working on our nines times tables – did you know there are some pretty amazing patterns in the nines?
If you look at the nines times table you might notice that the tens digit in the product is one less than the second factor. For example, in 9 x 3 = 27 , 2 is one less than 3. You might also notice that the digits in the product add up to 9. Eg: 2 + 7 = 9
So, if I haven’t memorized the times tables yet and I see 9 x 7 in front of me I think: 6 is one less than 7 so the answer is 60 something. 6 + 3 = 9 for the product is 63. Look, it works for all of them up to 9 x 10 and if you look at the product of 9 x 11 you will see that 9 + 9 = 18 and 1 + 8 = 9!
There is also the famous finger trick:
