In this unit, students are introduced to the notion of a repeating pattern. This is done by a number of means including the use of everyday objects. They are encouraged to create, describe and continue patterns.
- Describe patterns.
- Continue patterns.
- Create patterns.
In this unit, students are introduced to the concept of a pattern - a fundamental notion in mathematics. This notion is especially prevalent in research mathematics. Research mathematicians are trying to find things that occur regularly in some way. The results that they produce as theorems tell us about the patterns that will always occur under given circumstances.
Here we are concerned with introducing the basic ideas of a pattern. These are that patterns involve something that repeats, like ‘clap, shout, clap, shout, clap, …’ or ‘red, blue, yellow, yellow, red, blue, yellow, yellow, red, …’ or ‘5, 8, 11, 14, 17, …’ Now because patterns repeat there must be a rule that describes the repetition. For instance, after you’ve shouted, you clap and after you’ve clapped, you shout, or add 3 to get the next number.
As the students progress through school, they will meet many number patterns like 5, 8, 11, 14, 17, … and will be able to predict the next term by knowing the relationship between consecutive terms or by using a formula for finding the next term. This will eventually require algebra as algebra gives a succinct way of expressing such relations.
- Pasta shapes
- Nursery sticks
- Found equipment (Lego blocks, bottle tops, leaves, etc.)
- Chart paper and pens
This lesson is to be used to lay the foundation for the concept of pattern.
- Share a picture book with illustrations that show patterns.
What is a pattern? Can you see any patterns in our class.
- Go for a pattern walk. If available take a digital (or other) camera so patterns can be recorded, for example, path tiles laid in a repeating pattern, a repeating koru pattern on a traditional design.
- Return to class and construct an experience chart of the patterns observed.
Students are introduced to the idea of repeating patterns.
- Read the chart made yesterday. Make comparisons between geometric patterns and patterns that repeat. Be sure to explore repeating elements in cultural patterns such as tukutuku, kowhaiwhai or tapa cloth (siapo, ngatu, hiapo) patterns.
- Spend time as a class creating and talking about repeating patterns. Some ideas are:
- clapping patterns;
- body patterns (arms out, arms up, arms out, arms up);
- building colour patterns use counters, cubes;
- follow-the-leader patterns (hop, hop, jump, hop, hop, jump; stamp, stamp, clap, stamp, stamp, clap; etc.);
- joining dots to create patterns.
- Remember to encourage verbalization of the pattern. Encourage students to predict what will come next.
Students will freely create and explore repeating patterns.
- Begin this session with some of the pattern activities used in the previous session.
- Pattern making materials are spread around the room. Students are free to move to any centre and create repeating patterns. Go from student to student and ask:
Can you read your pattern to me?
What will come next?
How do you know?
- Watch for students who are unable to create repeating patterns. These students will need to spend some time copying and chanting patterns.
- Let the students share their patterns with the class. Encourage other class members to continue some of these patterns and describe the pattern.
Sessions 4 & 5
Students are given tasks to complete that require them to construct repeating patterns.
- Review repeating patterns. Read some patterns from the previous session.
- Give the students a choice of pattern tasks to do. Challenge the students to create patterns with more than two elements.
The tasks might include:
- creating wallpaper for the dolls’ house;
- making a patterned headband using a cultural design;
- designing a pattern for a dinner plate;
- creating a frieze for the classroom;
- creating your own tie with a repeating pattern;
- creating a belt with a repeating pattern;
- a pattern for the edge of a small tapa cloth.
- These tasks may be completed over several days.
Follow each session with a class sharing and discussion
time focusing on the repeating patterns.
