Lesson

Last Class Gabbie, Candace, Professor Mace and I explored the PDESAS website to gain an in sight on the standards we unpacked the week before. The standard I unpacked was CC.2.1.2.B.1  using place-value concepts to represent amounts of tens and ones and to compare three digit numbers.
Which means children must be able to understand place values in three digit numbers. They also must know how to represent tens place, ones place, and hundreds place.

The lesson I chose is 2nd grade number sense and place value. The objectives for this lesson are students will understand place value--the value of a digit depends upon its place or position in a number, and  Students should recognize the numbers 0 to 999. They will gain an understanding of the place values for ones, tens, and hundreds.

The lesson starts by giving a prompt. "Today we are going to strengthen our understanding of place value.  To do this, we will represent or show numbers in several different ways. Let’s begin with our NUMBER OF THE DAY place values and start with the number 137.  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.  I will use7one-cubes.  Now I have shown the number 137 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."

I believe this is a good way to teach students place value with three digit numbers. However, I would change this lesson to have it more children based. I would have the children do the steps with me instead of the teacher just modeling it at the front board.
