Stage 1 - Activity 4

Wake up

Description of activity

Students work out how many eggs are hidden in a basket after being shown the number of eggs outside the basket.
Whole class introduction:

  1. Students sit in a circle with one student in the centre as the ‘rooster’. Students sitting in the circle are the ‘farmers’. The ‘rooster’ has 10 eggs, a basket and a piece of cloth.
  2. The ‘farmers’ fall asleep.
  3. The ‘rooster’ hides some of the eggs under the cloth in the basket and leaves the remaining eggs outside the basket.
  4. The ‘rooster’ says ‘cock-a-doodle-doo’ and the ‘farmers’ wake up.
  5. The ‘farmers’ count the number of eggs outside the basket. They work out how many eggs are hidden in the basket.
  6. Students give their answer and explain how they worked it out.

Paired activity:

  1. In pairs, students repeat the activity several times using counters, a container and a piece of cloth.
  2. They record their results individually using pictures, numerals and/or symbols.

Extension: Students repeat the activity with 15 eggs.

The suggested time allocation for this activity is 30 minutes.

Context

Students have practised copying and continuing simple number patterns that increase or decrease. They have used patterns to assist counting forwards and backwards by ones, twos, fives and tens. Students have applied and discussed strategies to create combinations for numbers to 10.

Outcomes

MA1-1WM describes mathematical situations and methods using everyday and some mathematical language, actions, materials, diagrams and symbols
MA1-2WM uses objects, diagrams and technology to explore mathematical problems
MA1-3WM supports conclusions by explaining or demonstrating how answers were obtained
MA1-5NA uses a range of strategies and informal recording methods for addition and subtraction involving one- and two-digit numbers
MA1-8NA creates, represents and continues a variety of patterns with numbers and objects

Criteria for assessing learning

(These criteria would normally be communicated to students with the activity.)
Students will be assessed on their ability to:

  • use objects, diagrams or numerals to record addition and subtraction of one- and two-digit numbers
  • describe a given situation using mathematical language, materials and/or diagrams
  • explain how an answer was obtained
