TablesCalcViz
Read full descriptionHide full description
A tool for learners who rely on finger skip counting when doing more advanced arithmetic such as long multiplication or other methods that require recall of times tables facts. This provides both a visual and worded representation of a number as well as the numeral version and is restricted to the multiplication of two numbers from one to ten. This app is recommended to be used alongside the TablesViz strategy for learning times tables facts that can be found on the Capacitarpais website.
