Hello students and families,

Here is a quick demo of how to multiply using an open array. I’ve tried to cram 3 days of lessons into a 5 minute demo, so hopefully it makes sense!

Open arrays are so much fun!!!

no it ISN’T

Sorry, Anita – I’m with Zaiga on this one. Did you see the latest pencast on multiplication boxes? you might like that better.

Makes sense to me!

I prefer a calculator – handheld, phone, computer etc..

Or sometimes I call my mom.

Seriously, arrays are cool to keep it simple, and conceptualize.

Old school, alga rythims rule.

At first I thought multiplication was hard.But now that I know how to do it it gets easier every time we work on it.

I like the multiplication open arrays that you showed us it is a easy way to remember multiplication.

Hi,

I love this method!

me too!

Thank you for posting ! My 4th grader needed help with this and I had never heard of it….
