Video Tutorials

Number Stacks uses video tutorials to unpick the concepts behind each key skill.  As well as explaining the concepts behind the skills, videos work through example questions and then set out activities to help practise and consolidate knowledge and understanding.  Every video finishes with a fluency activity to assess whether the child is ready to move on to the next key skill.  Additional fluency activities are also available to download if required.  See below for a sample video tutorial and fluency activity.

Addition & Subtraction 3: Adding single digit numbers

Additional Fluency Activity

The video tutorials are designed to be watched by both adult and child together as part of the 1-to-1 session and all resources used in the videos are included in the resource kit.  This means that there is effectively no preparation time required before each session, meaning that adult time is spent where it matters most – working with the children!
