Today in math, we covered rounding whole number through the millions. For some, this was a bit of a challenge. So, this blog is just to help you guys work through the homework, as we worked it in class today:If I have the number: 793, 580, these steps will help you to round it correctly to the nearest thousand. (Since we had a fire drill today, we used the illustration of going up and down the ladder to escape the fire.)Step 1: Find what number is in the thousands place. (The 3 is in the thousands place.)Step 2: Draw your dot over the 3.Step 3: Look to your number ‘friend’ next door and draw your loop. My friend next door is number 5. He is going to tell me whether I need to go up or down the ladder to safety.Step 4: What are your rounding options? What is your ‘friend’ telling you? Should you go higher up the ladder to get away from the fire or lower down the ladder? My ‘friend’ number 5 is telling me to round UP because numbers 5 and up you have to round higher. For numbers 4 and lower, you have to round lower. So my options for this number are either to round up to 794,000 or round down to 793,000. Since my ‘friend’ is a 5, I have to round up to 794,000. (It is important to remember that any numbers before ‘the dot’ stay the same, and any numbers after ‘the dot’ change to zero.)Step 5: Write down your answer. So my answer is 794,000.We will also review this in class again tomorrow, to make sure that everyone gets enough practice and is confident rounding numbers to the millions. Happy Rounding!
