Max Maths, Year 1, Work Book, Doubling near numbers

In the Max Maths Year 1 Workbook, Practice 8 focuses on the concept of doubling numbers that are close to each other to find solutions to various problems. This exercise encourages young learners to understand and apply the concept of doubling and adjusting (either adding or subtracting) to get the correct total. For instance, question (a) asks the students to determine the total number of cubes by either doubling the number 4 and then adjusting by plus or minus one, or by doubling the number 5 and then doing the same adjustments. The aim is to circle all the methods that would lead to the correct total.

Similarly, question (b) inquires about the total number of seagulls by presenting options to double and adjust numbers close to the actual count. This pattern continues with questions (c) and (d), which deal with finding the totals for balls and cats respectively. Each question provides a set of strategies involving doubling a number near the actual count and then adding or subtracting one to reach the final answer. This exercise not only helps with understanding doubling but also with the concept of near numbers, enhancing mental arithmetic skills at an early stage of learning.
