More Tea: Doubles/Near Doubles


More Tea on the Hill!!! Doubles/ Near Double



 Welcome back to more Tea on the Hill!! As you all know, we have been working on Number Talks for a while now, but it gets better every week. This week we are working on Doubles/ Near- Doubles. You probably wonder what it is while you sip the Arnold Palmer. Take a good sip while I tell you how these Number Talks were mastered by two Pre-Service Teachers, not just one. We have Ms. Davonna a senior here at A&M, and Ms. Cassidy, a Junior here also at A&M. Ms. Davonna sounded a little nervous, but she mastered her part in getting the class to give her the answer to the problem. And, of course, you know we always start off with our fists to the chest because we are ready to start! The problem that was given was 998 + 999, which is 1,997. During this session, everyone agreed, and two ways to get the answer were defined. One of the ways is rounding 998 and 999 and subtracting two from one side and 1 from the other to get the answer. Another way was to decompose the numbers to get the answer and regroup. Now I know your cup is almost halfway finished but don’t drink it too fast. Remember we have Ms. Cassidy up next, who also taught a class today. Ms. Cassidy is familiar with the rules of Number Talks because this is not her first time teaching Number Talks, but her second time teaching it. The problem that was given was 998+998, which is 1996. During her session, students used two methods to get the answer which was rounding and subtracting to get the answer. Students defended this answer by rounding 998 and 998 to 1000, which gives you 2,000 and subtracting four to get 1996 as the answer. Now I know you're probably looking shocked and finished your cup of that good tea, but hang around and come back next week so we can top your cup off with lemon to set the tea off for next week!!

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
