The numbers will be automatically adjusted if the difference is less than 5.
Write the numbers 13 and 31 on the board. Which of these numbers is larger? How do you know? Remind the students that place value means that the value of a digit depends upon its place or position in a number. We can see that the digit 3 appears in different places in these two numbers so we know that the value of the 3 is different in each number.
What is the value of the 3 in the number 13? What is the value of the 3 in the number 31? Today we are going to strengthen our understanding of place value. To do this, we will represent or show numbers in several different ways. First, I will write the number in standard form.
Standard form is the usual way that we write a number.
Now I will use the base-ten blocks to represent the number. I first look at the hundreds place. I see that there is 1 hundred so I will use one flat. Next, I look at the tens place and see that my number has 3 tens. I will use 3 ten-sticks longs to show my number.
Finally, I will look at the ones place. My number has 7 ones. Now I have shown the number with my base-ten blocks. Ask the student to fill in the number and tell whether it is even or odd. Ask students how they determined whether it was even or odd.
The next section of the worksheet asks the students to write the number in words. Asking students write the number shows that they have working knowledge of the organization of numbers, place value and proves that they are able to communicate it.
A student communicating their answer and using mathematical terminology correctly proves that they have working knowledge of concept. If there is confusion, take them back to the base-ten blocks.
Have them count the number of hundred flats, or ten-sticks. I will first look at the hundreds. I see that I have a 1 in the hundreds place.
I also see that I used one hundred flat to show my number.
I know that has one group of a hundred, 3 groups of ten and 7 ones. The next step on my worksheet is to recall the number that comes before one less and after one more. The next way I will represent the number is using expanded form. You must remind the students that expanded form is like stretching the number out to show the value of each digit added together.
The digit 1 is found in the hundreds place so I know that its value is The digit 3 is in the tens place so its value is 3 tens or in other words, The digit 7 is in the ones place so it is worth 7. Ask students to fill in the expanded form on the ways to make portion of the worksheet.
Follow the same procedure but allow the student choose an elbow buddy to work with each group will have 2 worksheets to complete.
Allow the groups to complete the worksheet together. Rotate around the room being sure to ask questions to get students to explain their thinking.
Have the groups complete both the worksheets provided to each individual student total of 2 per group. Gather as a class and discuss what they found difficult and if and what concept they may have struggled with.Try five intriguing lessons to help your students read, write, follow and even evaluate directions.
