Properties of Shape - Triangle Activity - Starter

The "Fluent in Four - Revision" activity is designed for Year 4 students to consolidate their understanding of various mathematical concepts during the summer term. This particular session, scheduled for Week 9, Day 2, involves a series of arithmetic and geometry tasks. The arithmetic portion requires students to perform a subtraction involving thousands, tens, and ones, specifically subtracting 8 ones, 9 tens, and 6 hundreds from a number composed of three thousands, 5 ones, and twenty-six tens. Additionally, students are tasked with manipulating a given number by subtracting 4 tens, adding 5 ones, and subtracting 200, using place value counters as visual aids to support their calculations.

The geometry section of the activity engages students with the properties of a 2D shape, prompting them to identify the number of angles, right angles, obtuse angles, acute angles, and lines of symmetry it possesses. This exercise not only tests their knowledge of shapes but also encourages critical thinking and attention to detail. To further enhance their numerical fluency, students are presented with multiplication challenges, such as finding the product of a number repeated three times and solving a simple equation where a number multiplied by 3 equals 18. A table completion exercise reinforces their subtraction skills, where they calculate the difference between 7,834 and 682. These exercises are thoughtfully crafted to strengthen the pupils' foundational maths skills in a structured and engaging manner.
