This workbook will help students gain a deeper understanding of numbers up to 1,000. This includes being able to read and write these numbers, both in numerals and in words. They should also have a strong sense of place value and understand the concept of thousands, hundreds, tens, and ones. They should be able to compare numbers to determine which is larger or smaller and put numbers in order from smallest to largest or vice versa.

Teaching a second grader to write the expanded form of a number involves breaking it down into a fun and engaging process. Start by explaining that the expanded form is just a way of showing the value of each digit in a number. Use simple examples, like the number 345, and demonstrate how it means 300 + 40 + 5. Provide visual aids such as place value charts or use physical objects like blocks to represent hundreds, tens, and ones. Practice with various numbers, gradually increasing complexity, and encourage the students to write the expanded forms themselves. Reinforce the concept through interactive games, hands-on activities, and regular practice to build confidence and understanding.

The last page gives kids practice subtracting 1 less, 10 less, and 100 less with coins in a bank. This will help them understand place value by recognizing the value of digits in different positions (units, tens, hundreds). It also helps them grasp how subtracting affects each place value differently (subtracting 1 affects the unit's place, 10 affects the tens place, and 100 affects the hundreds place).
