Number 3: Mathletics.
I know lots of schools buy into online Maths programmes.
At my current school the children have their own logins for Mathletics, which they take through the school so it can record their progress.
As a teacher, it is a genius homework creator. No searching for 3 differentiated worksheets every week. You simply choose the area of Maths they are working on, and set tasks for specific learning objectives. They've even created workbooks which you can print for your topic, if there's any children without access to the internet. Simple! What makes it even better, for each topic there are something easier and something harder options.
There are also game options for them to practise key skills, and if they want to go back to a topic they can search for it themselves. Most activities are now available in tablet mode too!
What my class particularly love are the certificates, they can earn Bronze, Silver and Gold certificates which you can print off for them. We have an awards ceremony in class once a half term to celebrate the children's hardwork.
On the topic of Maths, here are my top 3 go to activities during Maths activities on the iPads:
1. Snappy Maths
2. Hit the button
3. Espresso Maths games
What are your best apps/ websites to help with Maths teaching?
