In the space to the right, draw a place value chart. Show 6.22 using dots. (Tip- only draw the places you need- keep it simple.) 2b. Explain why the 2s in the number above have different values. Use words and numbers. Use words like ten times as much and one tenth in your explanation. For example: In the number 0.55, five tenths is ten times as much as five hundredths and five hundredths is one tenth as much as five tenths. 3. Multiply 6.22 x 10³ Explain how the value of each digit changed when you multiplied the numbers above and why you added that amount of zeros. Draw a place value chart to show your understanding of how the numbers shift to new places.

6 Thousands Hundreds Tens Ones Tenths Hundredths The values of each digit changed when I multiplied. Each increased by 1, ones became 6 thousands, 2 tenths became 2 hundreds and 2 hundredths became 2 tens. I only added one zero because I needed a place holder in the ones place. Without the zero the number would be Divide ² = Explain the shift of the digits by drawing a place value chart. Explain how the value of each digit changed when you divided. The values of each digit changed when I divided. Each decreased by Ones Tenths hundredths thousandths Ten ones became 6 hundredths, 2 Thousandths tenths became 2 thousandths and thousandths became 2 ten thousandths.
