The Meaning of Four Continues


Good evening,

In kindergarten this week, we are continuing with the concept of four on our tens frame. This time both levels of the tens frames were use.  The tens frame below is one of the examples from class.
Students are beginning to understand that four dots arrange anywhere on the tens frame is four. 
Only one student continues to struggle with subitizing four:
Teacher: So how many do you see.
Student: I see three over here and one more over there to the right.
Teacher: Well, lets count the dots.
Student: One, two, three, and (with hesitation) four.
Teacher: So now how many dots do you see?
Student: I see four.

After having this student to actually count the dots, she realizes that there are four dots and not three and one more.
A couple students manipulated the dots to where they could recognize immediately there were four. This is fine. However, I want them to move from counting to actually readily knowing that there are four dots. Until then, the kindergarten teacher and I will continue using NT to build student capacity to subitize and quantify numbers.

    Love to see that you are working with Kindergarten

      I started a couple of years ago with new teachers. But could not get in depth.

    Yes I have one that still counts so I do the quick images for him. That way he knows he doesn't have enough time to count.

      Awesome. I'm going to model that for the k teacher. Instead of going to five.

Let’s Talk about Numbers! Embedding Number Talks into Pre-service Teachers Mathematics Methods Course As a classroom teacher, I saw the essential benefits of including mathematical discourse in my mathematics classroom. My elementary students were engaged with solving problems and having discussions about their approaches. As a faculty member, allowing my preservice teachers to have conversations about numbers is even more essential. Preservice teachers come with diverse experience and preconceived feelings about mathematics. They bring their feelings into college and into their teaching practices. These feelings include the following: ·          I can’t stand math! I don’t want to teach it. ·          I love math. It was my favorite subject in school! ·          There is only one way to do math!   My goal is to help develop mathematical thinkers, and, in turn, give them the necessary pedagogy to build mathematically thinkers. Hopefully, my preservice teache

My Answer is Five!

Several times a week I offer study sessions to my pre-service teachers for Praxis Multiple Subject Mathematics, one of five tests elementary teacher candidates have to pass to teach.   My preservice teacher came across the following practice problem from Math Made Easy:   Jan ran 30 blocks in 6 minutes. Assuming that she ran at a constant speed, how long did it take Jan to run one block? My student commenced to solving the problem. She said so I divide 30 by 6 to find out how much time it will take to run 1 block and the answer is 5. After reading the problem again. I ask her to notice the problem. Remember if the speed is constant, should it take her 5 minutes to run 1 block?   She thought about and decided it did not make sense. I am writing this in support of one of the Standards for Mathematical Practices from the Common Core State Standards . Reason abstractly and quantitatively.   Students proficient in mathematics make sense of the relationship of quantities in p

Number Talks with Fraction

Image
This post is based on the last class session for this semester. We went out with a bang. We tackled NT with fractions. We actually started our talk about fractions the previous class session. Today was more of a review for the final. After much practice order fractions without determining alike denominators and operations with fractions using models, my PST (Pre-service Teachers) engaged in a NT involving fractions. The following is a conversation with adding fractions:   1/4 +1/2 Teacher: How did you get 3/4/ ? PST 1: I know that 1/2   is equal to 1/4 + 1/4which is 2/4.  So I used 1 /4  + 1/4 + 1/4. Therefore   it equals to 3/4.   PST 2: I just found that common denominator which is fourths. Since the first fraction already has fourth, I don’t have to change that fraction. But the second fraction is ½. The second fraction has to be changed to the new fractions that is equivalent. The equivalent fraction is 2/4 . So 1/4 + 2/4   is 3/4  .   Both student used equivalenc
