Schools are starting, many still partly or totally online. Our students with dyscalculia thrive by handling manipulatives themselves and over the summer many parents have been proactive by buying a set of the materials most used so the tutor can demonstrate and can see how the student builds the same and after that can show how to work out his/her own answers.     We can’t expect parents to purchase the variety of manipulatives a tutor has, so we often need to throw in some online manipulatives. 
Here are the websites with virtual manipulatives I am using the most:

• NumberShapes has interactives with number lines, including double number lines to help visualize proportional thinking, attractive looking subitizing using colored eggs, also images, tasks, apps, and games  http://www.numbershapes.com/
• MathsBot, Tools for Maths Teachers has arguably the largest series of manipulatives,  and tools https://mathsbot.com/ also help for GCSE, fact practice drills, and more
• Mathigon has activities that include virtual manipulatives at the polypad https://mathigon.org/polypad base ten blocks, number bars, fraction bars, algebra tiles, pentominoes, and tangram that you can place on a white background or in a square grid, save your work and share or with your student by email 
• The illuminations website from the NCTM has a large number of interactives, searchable for topic and level  https://illuminations.nctm.org/

If you have a gem you want to share with your fellow Dyscalculia Tutors, please drop me an email and we’ll share them. Happy online tutoring!
