This short task was used as a starter for my Grade 9 (MYP 4&5) students to practice the ‘verify’ steps for Criterion B (Investigating Patterns). The topic investigated is finding the coordinates of the vertex of a quadratic given its equation in completed square form.

Given the graph of a function, students need to complete the table to by identifying whether the transformation is a stretch, reflection, translation or rotation. This was used as an starter, before looking into how the equation of a function changes with different transformations. Solutions included.

This short task was used as a starter for my Grade 9 (MYP 4&5) students to practice the ‘verify’ steps for Criterion B (Investigating Patterns). The topic investigated is finding the y-intercept of a quadratic graph. It goes through the steps of verifying (prediction, actual, comment)
