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