The workbook "Numbers to 1,000" reviews basic counting skills and then introduces the concept of hundreds, in addition to tens and ones. This will help students grasp how numbers are composed and decomposed. Lessons cover reading and writing numbers up to 1,000 in numerals and words. Activities include skip counting by 5s, 10s, and 100s to enhance number sense and fluency. Visual aids such as number lines, base-ten blocks, and charts would improve understanding of this workbook.

Students encounter problems designed to build their number sense and strengthen their understanding of place value. For example, they could work on problems that ask them to identify the value of digits in different positions within a three-digit number, such as determining that in the number 472, the digit 4 represents 400. Another type of problem could involve ordering a set of three-digit numbers from smallest to largest.
