This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit pupils will represent numbers 6 - 10 by partitioning in different ways. They will learn what odd and even numbers are and how they can be partitioned. They will identify a missing part when a whole is partitioned into two parts where one of the parts is known.
Lesson Summary
You will learn to count sets of objects within the numbers 6 to 10 set and record the numeral to show the quantity in each set.
Key Notes
- Count a set of 10 objects reliably.
- Develop fluency in counting and securing the cardinality principle and the stable order principle.
- Revisit and secure understanding of how the number tells the quantity of a group.
Vocabulary To Learn
- Count: Saying the numbers in order to find the total amount in a set.
- Number: A count, measurement or idea of a value.
- Numeral: A numeral is a symbol or name that stands for a number.
- Number name: A number word is the word we say for that number, so the number word for 2 is two.
Common Mistakes To Avoid
- Children may not be secure with the principles of counting.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Count a set of 10 objects reliably. Develop fluency in counting and securing the cardinality principle and the stable order principle.
2. Use this key word in a maths sentence and explain it clearly. 'Count'
Saying the numbers in order to find the total amount in a set. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Children may not be secure with the principles of counting. Correction: Encourage any and all opportunities to count small collections of objects considering ways in which to count efficiently. Model counting using one-to-one principles and strategies such as organising collections to support counting all.
