The Year 2 10s on the Number Line to 100 PowerPoint guides both teachers and children through the lesson, including use of the varied fluency, reasoning and problem solving, deeper reasoning and scaffolded resources. Key learning information about this step:
Key Vocabulary
number line: A straight line which has numbers placed at equal points. Most number lines begin at 0, although this is not always the case.
interval: The space between two divisions on a number line. Every interval on a number line is worth the same amount.
multiples of 10: Counting in groups of 10. The ones digit will always be a 0.
count forwards: To count on. The numbers will get bigger or greater (0, 1, 2, 3, 4).
count backwards: To count back. The numbers will get smaller (4, 3, 2, 1, 0).
Varied Fluency
Knowledge Organiser
• Designed to support all children via key information and examples.
Scaffolded Examples
• Completing a number line, finding what each interval is worth, then reading the number an arrow is pointing to.
Support
• Q1: complete a number line with two missing 10s.
• Q2: read one arrow, with a middle value given.
• Q3: draw one arrow, with a middle value given.
Core
• Q1: complete a number line with three missing 10s.
• Q2: read two arrows, with only the end points given.
• Q3: draw two arrows, with only the end points given.
Stretch
• Q1: complete a number line with seven missing 10s.
• Q2: read three arrows, with only the end points given.
• Q3: draw three arrows on a line with nine intervals.
Reasoning and Problem Solving
Support
• Q1: Reasoning - explain whether an arrow has been read correctly, with a middle value given.
• Q2: Reasoning - explain whether a label on a number line is correct, with a middle value given.
• Q3: Problem Solving - find three ways to complete a number line with four intervals.
Core
• Q1: Reasoning - explain whether an arrow has been read correctly, with only the end points given.
• Q2: Reasoning - explain whether a label on a number line with seven intervals is correct.
• Q3: Problem Solving - find three ways to complete a number line with seven intervals.
Stretch
• Q1: Reasoning - explain whether an arrow has been read correctly, with more intervals.
• Q2: Reasoning - explain whether a label on a number line with eight intervals is correct.
• Q3: Problem Solving - find three ways to complete a number line from four conditions.
Deeper Reasoning
The questions in this set focus on solving problems with number lines to deepen understanding in identifying, representing and estimating numbers using different representations, including the number line.
