Singapore Math Source - a blog from a national trainer

Cassy Turner is a trainer in Singapore Math that has a blog I have found very helpful in the past week. The last two posts I have added have come from this site. I have been in contact with her and she is a great source of information on Singapore Math. If you use Twitter, you can follow her: @Cassyt.

Singapore Math Blog from Math in Focus trainer

Kelli Trainer has a Singapore Math Blog. She was a trainer for us in late July and in October. You can subscribe, so you will get notification when a new post has been added. Look at her post dated November 28 to learn about the free online math interactives at MathFrames. Great visuals and explanations to see what is available. There are games for number bonds, multiples, patterns, missing digits when multipliying, etc.
Tobe Joffe recommened MathFrames to me this week. Now you can get an overview on one page before you try it. http://www.mathsframe.co.uk/free_resources.asp

Polar Express Math

An elf that wishes to remain anonymous shared this with me today. There are 10 word problems that relate to the Polar Express book. Most could be solved with Model Drawing. The teacher changes out the names used in the problems with students' names. This teacher will do one a day the last two weeks before Christmas break. Ten engaging and relevant problems that would be most appropriate for 2nd - 3rd grade. Here are Problem 1 and Problem 9 as a sample:

1) When Kelly got on board the Polar Express, there were 31 seats available. The train has a total of 159 seats. How many seats were already filled?

9) As Santa and his reindeer took off into the sky, they were traveling at 431 miles per hour. The farther away they got the faster they would go. The Sky Officer measured Santa traveling at the speed of 900 miles per hour. How much faster was Santa traveling than when he first took off into the air?

Thank you so much for passing this on!
