How many units and/or tens are needed to make the number 3?
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: Since the number we want to represent is 3, and 3 is less than 10, we do not need any tens to form the number.
Step 2: We need to represent the number 3 with units. Each unit represents a value of 1. Therefore, we require 3 units since .
Step 3: Among the answer choices, the correct choice is the one that indicates using only units to make up the number 3. This matches choice 4: "Three units".
Therefore, the solution to the problem is three units.
Three units
What number do the blue squares below represent?
You only need tens when your number is 10 or greater. For numbers 1-9, you only need units! Think of it this way: 3 is just 3 ones, but 13 would be 1 ten and 3 ones.
Units and ones mean the same thing! Both represent single items with a value of 1. Some teachers use 'units' and others use 'ones' - they're interchangeable terms.
Simply count up your units to see if they equal your target number. For 3, count: 1 unit, 2 units, 3 units. Perfect match!
Technically yes, but it's not practical! While 30 units equals 30, we group every 10 units into 1 ten to make counting easier. So 30 = 3 tens + 0 units is the standard way.
Choose the simplest representation! For numbers 1-9, always use units only. For 10 or more, use the combination of tens and units that makes the most sense.
