AN02 Activities



 The Root of the Problem from NRICH  Investigate the sum of a complicated looking expression with 100 terms with radicals. You don't need to know about series to solve this one.
 Pedantic Arithmetic Rules  Why/when should we reduce fractions? Why does a radical in simplest form not have a radical in the denominator? (see the bottom of page 274 in the PreCalculus 11 textbook for Radicals in Simplest Form) It would be a worthwhile activity to discuss this with students so they understand it instead of just memorizing a list of rules.

 Increasingly Difficult Questions (Surds) from Dave Taylor  These questions increase the difficulty of questions at an increased rate as students work through an exercise,
AN03 Activities
 Who Wins the Race from Illustrative Mathematics  Alice and Briana each participate in a 5kilometer race. Each of their progress is modeled by an expression. Who wins the race?
