Developing Grade 9 Math Skills

To develop skills in math, a Grade 9 student must focus on the newly introduced topics such as quadratics, trigonometry, simple and compound interest etc. This would really help them to score well in their school exams as well as national level competitions.

Quadratics: This involves multiplying two binomials whose result is a quadratic expression, factoring quadratic expressions, solving quadratic equations using completing squares, etc.

Trigonometry: Trigonometry in Grade 9 starts from the introduction like defining trigonometric ratios, finding them given a right triangle, finding the missing sides, and missing angles.

**Simple and Compound Interest: **This is one of the important topics of financial/commercial math which is very useful in real life as well while dealing with money, investments, debts, etc. There are mainly two types of interests called simple and compound interests which have different formulas to calculate them in different cases.

The 50 puzzles in this printable worksheet focus on all of these topics. Answers are also provided.
