This lesson develops the concepts of length and area. Particular attention is given to proving why two areas are or are not equal.

The lesson begins with three questions regarding area that students must classify as ‘sometimes, always, or never true’. An example is ‘if you join the midpoints of the opposite...

This resource develops the concept of substitution of integers, fractions, decimals, and directed numbers into inequality statements in order to test their validity. Students also represent inequalities algebraically and in words.

An initial question that students work on is representing the statement

This is a concept development lesson that is designed to assess how well students understand the concepts of:

• Equally likely events
• Randomness
• Sample size

The central theme of the lesson is to address common misconceptions relating to probability. The main activity is to...

This lesson develops concepts relating to radicals. In particular, students will enhance their understanding of:

• Use the properties of exponents, including rational exponents and manipulate algebraic statements involving radicals.
• Discriminate between equations and identities.
  In this...

This lesson develops the concept of reasoning about the properties of rational and irrational numbers. In particular, students will enhance their understanding of:

• Finding irrational and rational numbers to exemplify general statements.
• Reasoning with properties of rational and irrational...

This resource requires problem solving using skills in forming and factorising expressions.

Students investigate the sum of four consecutive numbers. Initially this is done using numerical examples. There are a series of statements for students to classify as ‘sometimes true’, ‘always true’, or ‘never true...

This list of key questions, from the National Strategies, helps teachers to focus on and evaluate their science department's systems of tracking students' progress. Using these questions, the science department considers the effectiveness of their strategies, impact on students' progress and identify those who need...

These videos guide you through the process of evaluating the impact of changes you make to teaching approaches in your classroom. The evaluation approaches described here will enable you to tell whether new approaches are more effective than what they have replaced. You'll be able to make evidence-informed...

This resource contains an evaluation report on the two-year mentoring pilot programme for science and mathematics teacher trainees and early career teachers funded by the Training and Development Agency for Schools (TDA) which started in July 2009. 'Starting Out' was delivered by the Learning and Skills Network (...
