In this Year 5 Number Line to 1,000,000 lesson, children read, write, order and compare numbers to at least 1,000,000 and determine the value of each digit.
The Year 5 Number Line to 1,000,000 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 lines: A horizontal or vertical line which has numbers placed at equal points. Number lines can be used to show either positive or negative numbers. Most number lines begin at 0.
interval: The distance between two marked points on a number line. All the intervals on one number line are equal in size.
midpoint: The point on a number line that is exactly halfway between the start and end values.
estimate: To make a sensible guess at what the answer could be. You usually estimate the answer by rounding the numbers to make the calculation easier. Another word for estimate is approximate.
Varied Fluency
Knowledge Organiser
• Designed to support all children via key information and examples.
Scaffolded Examples
• Counting intervals, reading an arrow and finding a midpoint.
Support
• Q1: Two number lines; start from 0; one interval given; related facts used.
• Q2: Two number lines; start from 0; find midpoint; difference is given; related facts used.
• Q3: Two number lines; estimate number; all divisions labelled; starting from 0.
Core
• Q1: Two number lines; starting from 0 and multiple of 100,000; no interval given.
• Q2: Two number lines; not starting from 0; find midpoint.
• Q3: Two number lines; estimate number; no midpoint labelled; starting from 0 and other multiples.
Stretch
• Q1: Two number lines; not starting from 0; no intervals given.
• Q2: Two number lines; not starting from 0; find midpoint; crossing boundary.
• Q3: Two number lines; estimate number; not starting from 0.
Reasoning and Problem Solving
Support
• Q1: Reasoning - explaining whether the midpoint of a number line is correct; the difference between the two ends is given.
• Q2: Reasoning – missing numbers on a number line; start and end point given; 4 intervals of 100,000.
• Q3: Problem Solving - finding possible end numbers on a number line; starting at 0; clue given.
Core
• Q1: Reasoning - explaining whether the midpoint of a number line is correct; no difference given; multiples of 100,000.
• Q2: Reasoning - missing numbers on a number line; start and end point given; 8 intervals of 50,000; not multiples of 100,000.
• Q3: Problem Solving - finding possible end numbers for a number line; does not start at 0; clue given.
Stretch
• Q1: Reasoning - explaining whether the midpoint of a number line is correct; ends are not multiples of 10,000.
• Q2: Reasoning - missing numbers on a number line; start and end point given; 10 intervals of 50,000.
• Q3: Problem Solving - finding possible end numbers for a number line; does not start at 0; clues given.
Deeper Reasoning
The questions in this set focus on problem solving with number lines to deepen understanding in reading, writing, ordering and comparing numbers to at least 1,000,000 and determining the value of each digit.
