Radical Golf: Estimate square roots to one decimal place You get a hole in one (1 pt) if right on. If 1 decimal off, you score a 2. If 2 decimals off, you score a 3. If more than 10 off, 10 is highest score. Goal is to score the lowest over 18 holes! No calculators allowed Individual work/game Individual scores kept in notebook

Radical Golf. Estimate to one decimal place square roots Radical Golf. Estimate to one decimal place square roots. Make an 18 hole scorecard. Write down students’ guess. They get a hole in one (1 pt) if right on. If they are 1 decimal off, then they score a 2. If 2 decimals off, then a 3. If more than 10 off, 10 is highest score. Goal is to score the lowest over 18 holes. Kids have fun with it.
