Array Multiplication

Here are the students of grade 4, hard at work coaching  their math partners in the fine art of Array Multiplication.  Scroll down to the bottom of the post to see some student work samples.

Want to see it in real time?  Give your child a 2-digit by 1-digit multiplication question, and ask them to show you how they would use an open array to find the answer.

Weekly Updates

The pages across the top of the blog have been updated with information about the coming week.

I would especially encourage you to take a look at the Math Page – where I’ve posted a Slideshow and a video screencast on topics that we’ll be working on this week.


Feedback on Showbie

If you haven’t had an opportunity recently, please check your child’s Showbie account.



(let me know if you need their login and password) – in the Math class – there is some feedback about some work they did on Multiple Choice questions in Geometry… and – I just put in some information about how they’re doing with multiplication fact mastery, and what their next steps ought to be – please encourage your child to take a look as well – I will do the same at school.  Thanks!

Geometric Properties – Multiple Choice Proofs

Claire has given me her permission to share her outstanding answer to a multiple choice question that we worked on last week – she did a screencast on Explain Everything where she proved that (B) was the correct answer, and also proved why (A), (C) and (D) were incorrect – watch and learn how an expert screencast explaining your thinking in Math is put together 🙂 – thanks for sharing, Claire!


Catch me if you can!

Yesterday, we talked about how the only way to get multiplication facts  into your head is to practice them – something I, like most people my age, did when I was a kid – and they’re still in there.  I issued a challenge to the kids yesterday – match (or beat) my record on the timed drills. Shouldn’t be too tough – after all- I’m old, and my reflexes are slow – right ? ?  I took two tests yesterday – one on each of the two multiplication drill apps I showed them – here’s are some screenshots of my scores – can you beat my record?

Here’s my score on MathCards – Mixed Drill, Level 2, 50 questions in 2 minutes, 24 seconds.

And on My Math App – Mixed Facts – 50 Questions – a score of 15130 in 2 minutes, 13 seconds
