This lesson plan will cover in part standard 2.G.3. We will introduce the terms "half" and "fourths". Students will discriminate between equally divided wholes and nonequally divided wholes. Students will be assessed to determine if they can accurately identify and divide into halves and fourths.
Open Middle tasks provide opportunities for student to approach a mathematical task using different strategies and representations. They can be used as a warm-up/closing activity, as a formative assessment, or to facilitate discourse and discussion and get insite into student thinking and problem solving. These tasks provide a great opportunity for student to engage with the Standards for Mathematical Practice.
