Use the instructional video to guide your students through the activity. Alternatively, continue with the direct

instructions below.

Introduce or review place value with your students. Show students the number, 473.258. Tell students the

number is four hundred seventy-three and two hundred fifty-eight thousandths. Explain that you know the name of

the number because each digit represents a different amount or value. To understand the value of this number

you need to be aware of the decimal point. On the left side of the decimal point are the whole numbers and on the

right side of the decimal point are the parts. The place a digit is in tells you the value. Guide students to look at

the numbers to the left of the decimal, the three is in the ones place so this number has three ones (3X1) or three.

The seven is in the tens place, so this number has seven tens (7X10) or seventy. The four is in the hundreds

place, so this number has four hundreds (4X100) or 400. Now guide students to look at the numbers on the right

side of the decimal. Since these numbers are all parts, you can not have any whole numbers. Instead parts are

represented as tenths (2/10), hundredths (5/100), or thousandths. (8/1000). The takeaway is that a decimal

number is made up of whole numbers and parts. Each digit in a decimal number has a different value or amount.

Tell students for today's activity they are going to make a number randomizer using intersecting lines, Color

Codes and their Ozobot. The number randomizer will have multiple possible pathways for Ozobot to follow. Each

pathway will lead their bot to a different digit. They Will then build a number to the thousandths using the digits

their bot leads them to.
