Drawing and interpreting histograms (inc. worksheets)

An interactive geogebra applet that aids the modelling of drawing and interpreting histograms. Includes equal class widths (normal bar charts) and unequal class widths (histograms). Please see the video for how the use the teaching aid. I have also included two scaffolded worksheets. One for reading and interpreting histograms and one for estimating quartiles and percentiles. The geogebra applet is attached but if you don’t have it installed then the web link is also attached so you can use th

Forming quadratic equations from probability trees (inc. worksheet)

Fully interactive question generator and solver. Use this to model how to set up and solve worded quadratic equations in the context of a probability tree. Randomly generate questions or specify with/without replacement and same/different colours (see image). Model the solutions line by line by using the controls to reveal each step. This is an interactive geogebra applet but if you don’t have geogebra installed (free) I have also included the web link so that you can use this applet in a web br
