We are trying to use an inspiring ideas to get students to engage more in math. So we start with a world task and then have focus workshops. E.g. If I noticed students struggling identifying fractions such as halves or quarters then I could pull that group aside and do some specific teaching.
This is the image we used for the first part, halves, thirds, sixths and ninths then we added another column of triangles to teach halves, quarters, eighths, thirds and sixths. These are the slides we used.
