Doubling Numbers to 10
Understanding the concept of twice as many and finding doubles of numbers up to 10.
Key Questions
- Analyze what happens to a number when we double it.
- Predict the double of a given number.
- Explain how doubling is related to adding the same number twice.
National Curriculum Attainment Targets
About This Topic
Asking and testing is the heart of 'Working Scientifically'. In Year 1, this involves encouraging pupils to ask simple questions and recognize that they can be answered in different ways. They learn to perform simple tests and use their observations to suggest answers. This is a foundational skill that applies to all areas of the science curriculum.
Students move from 'I wonder...' to 'How can I find out?'. They learn about 'fairness' in a very basic sense, for example, if we are testing which ball bounces highest, we must drop them from the same height. This topic comes alive when students can physically model the patterns of a fair test through trial and error.
Active Learning Ideas
Inquiry Circle: The Great Splat Test
Groups test which material makes the best 'landing pad' for a playdough ball. They must agree on how to make the test fair (same height, same ball) and then record which material kept the ball from squashing.
Think-Pair-Share: Is it a Science Question?
Give pairs a list of questions (e.g., 'What is my favorite color?' vs 'Which magnet is strongest?'). They must sort them into 'Science Questions' (we can test it) and 'Opinion Questions' (we just feel it).
Simulation Game: The Fair Test Referee
One group performs a 'bad' experiment (e.g., jumping from different starting lines). The rest of the class acts as 'referees', blowing a whistle when they see something 'unfair' and suggesting how to fix it.
Watch Out for These Misconceptions
Common MisconceptionStudents often think an experiment is 'wrong' if their prediction didn't happen.
What to Teach Instead
Teach that a 'surprise' result is actually the most exciting part of science! Peer discussion about 'why' the result was different helps them value the process over the 'correct' answer.
Common MisconceptionChildren may try to change multiple things at once in a test.
What to Teach Instead
Use the 'One Change Rule'. If we change the ball, we must keep the height the same. Physical 'checklists' during the activity help them stay focused on one variable.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.

Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
