**Sequences and series:**

In this unit we will look at the power of sequences to describe patterns.

**Syllabus points: 1.2, 1.3, 1.4 **

Sequence and series are a good starting point to begin the syllabus as they are quite accessible – and the shared content across the different courses allows students t change courses early on.

I have made 13 worksheets and activities to assist with sequences lessons. They are:

- A Sequences Puzzle [investigation]
- Arithmetic sequences and series 1
- Arithmetic sequences and series 2
- Compound interest
- Geometric sequence and series 1
- Geometric sequence and series 2
- Mixed exam style questions SL
- Mixed exam style questions HL.
- Some sequence puzzles [short]
- Test: Sequences
- Treasure hunt: compound interest
- Treasure hunt: arithmetic
- Treasure hunt: geometric

**A sequences puzzle**

Note: This is an activity which lends itself to a classroom investigation or for homework. This introduces the idea of how an exploration could begin.

**Arithmetic sequences and series 1:**

Note: This is a short worksheet which can be used in lesson or for homework. It covers syllabus point: SL 1.2 with a focus on arithmetic sequences.

**Arithmetic sequences and series 2:**

Note: This is a short worksheet which can be used in lesson or for homework. It covers syllabus point: SL 1.2 with a mixture of sequences and series.

**Compound interest:**

Note: This is a short worksheet which can be used in lesson or for homework. It covers syllabus point: SL 1.4 with a mixture of compounding problems.

**Geometric sequence and series 1:**

Note: This is a short worksheet which can be used in lesson or for homework. It covers syllabus point: SL 1.3 with a mixture of geometric sequences and series.

**Geometric sequence and series 2**

Note: This is a short worksheet which can be used in lesson or for homework. It covers syllabus point: SL 1.3 and SL 1.8 with a mixture of geometric sequences and series including sums to infinity.

**Mixed exam style questions SL:**

Note: This is a short worksheet which can be used in lesson or for homework and gives some past paper SL style questions covering SL1.2-SL1.4 and also SL1.8.

**Mixed exam style questions HL:**

Note: This is a short worksheet which can be used in lesson or for homework and gives some HL past paper style questions covering SL1.2-SL1.4 and also SL1.8. These include more problem solving examples.

**Some sequence puzzles [short]**

Note: This can be used as a student worksheet, or as a teacher starter activity to get students investigating number puzzles.

**Test: Sequences**

Note: This is a one hour test on the sequences topic – designed for SL students.

**Treasure hunt: Compound interest**

Note: This is an activity which can be done in pairs or as a whole class activity. Students solve a mixture of compound interest problems.

**Treasure Hunt: Arithmetic sequences**

Note: This is an activity which can be done in pairs or as a whole class activity. Students solve a mixture of arithmetic sequence problems.

**Treasure Hunt: Geometric sequences**

Note: This is an activity which can be done in pairs or as a whole class activity. Students solve a mixture of Geometric sequence problems.
