Let's solve the problem step by step.
The task is titled
"Four Ways to Write a Number!" and asks you to express each given number in four different ways:
1.
Standard Form – The number as it's normally written (already provided).
2.
Place Value – Breaking down the number by place values (ones, tens, hundreds).
3.
Expanded Form – Writing the number as the sum of its place values.
4.
Picture – Drawing a visual representation (we’ll describe this since we can't draw here).
We'll go through each number one by one.

✔ Explanation:
-
Place Value identifies how many ones, tens, and hundreds are in the number.
-
Expanded Form shows the value of each digit added together.
-
Picture uses base-ten blocks (hundred flats, ten rods, unit cubes) to visually represent the number.
This helps students understand that numbers can be represented in multiple ways, reinforcing number sense and place value concepts.
Parent Tip: Review the logic above to help your child master the concept of place value worksheet 2nd grade expanded form.
