Year 2, Term 4: Algebra and algorithms

Focus: Formulas

Scope and sequence: Algebra, Algorithms

Learning intention: Students explore number patterns as an introduction to algebra and algorithms.

NSW Syllabus
Australian Curriculum (version 9.0)
"A student describes, follows and represents algorithms to solve problems." (ST1-3DP-T)
"Students learn to recognise, describe and create additive patterns that increase or decrease by a constant amount, using numbers, shapes and objects, and identify missing elements in the pattern." (AC9M2A01)

Week 1

Number formula activity

Number guessing game

The game is played again with a student running the game.

The next stage with this activity is to contrast good guesses such as "Is it lower than 50?" with random guesses such as "Is it 87?"  This can then be used as an introduction to algorithms where the aim is to narrow down the options.

Algorithms in other curriculum areas

The following video (2:09) shows how algorithms are also used in other curriculum areas.

Week 4

Algorithms and pseudo code

The following video (4:58) explains algorithms using a counting example and pseudo code.
