Product Description

I love tasks which encourage students to discuss and reason mathematically. This Geometric Sequences Sort & Stick Task is a great way for students to do this while practicing and using their geometric sequences knowledge at the same time.

For this task, students cut out the question cards and sort them in the grid according to different properties before sticking them down. Along with good systematic reasoning this is a great review task for pair or group work. This cut, sort and stick activity allows students to discuss different properties of geometric sequences and work together to find solutions.

-- Students should be familiar with the following concepts to be able to complete the task:

geometric sequences, common ratio (r), nth term (Un), converging and diverging sequences, |r|<1, first term, finding a specific term, sum of the first n terms (Sn) and the sum to infinity.

-- Terminology used includes:
geometric sequence, converging/converges, diverging/diverges, even, common ratio, first term, sum and summation.

Contains:

• Four 3 x 3 Grids

• Four sets of question cards (with 9 cards in each set). These are paired with each grid.

• Solutions: the possible placements of all the cards and all solutions which put a single card in each of the nine spaces to complete the grid.

Suggested use:

Each set of question cards and grid are linked. Give each student a matching set. For example a student would need both CARD SET 1 and GRID 1. After cutting out the question cards, students discuss how to arrange them on the grid and try to find an arrangement where the grid is filled with one card in each space.

Differentiation

A great extension task is to ask students to create their own set of question cards to fit a given grid or to create their own grid for a set of cards. Challenge your students to make a perfect arrangement where the grid is filled with only one card in each box.

For support you could give students definitions of the key terms.

Alternatively they could just work out all the possible places for each card, allowing more than one card per box, and some empty boxes.
