What Size Is It? looks at how we can measure different things: size, height, weight, capacity, time, speed. It encourages children to think critically, taking a first look at mass and density, and stimulates discussion about the words we use to describe size. Bright, eye-catching and clear photographs encourage children to look at Maths in their environment and makes the books accessible for a wide age range. Simple text incorporates mathematical terms and builds children's awareness of numbers and counting. Great for preschoolers.
