MATHEMATICS ~ MRS. MICHELLE MARINI ~ December 2017

 

Deeper learning occurs when students are given the opportunity to make sense of mathematics in their own
ways such as making convincing arguments, and critique and build on the ideas of their classmates. When students
talk about numbers, they develop the sense that mathematics can be both meaningful and fun.
Accountable Talk strategies have been introduced across the content areas at Tashua School. Our
mathematicians use this platform to develop their math talk skills in order to build number sense. Number sense is
the ability to play with numbers, meaning students can visualize problem solving, perform calculations quickly, and
are flexible in their mathematical strategy. Students who have strong number sense can solve problems in more
than one way and check that their answers make sense. During a number talk, students are thinking, asking their
peers questions, and explaining their own thinking while the teacher facilitates the learning goals. You can support
your child by playing games that support math talk. One example could be playing the game “Guess my Number.”
See a sample of how to play the game below. The best part is that it can be played anywhere (i.e.-waiting in lines
while holiday shopping), no materials are needed, and it could be differentiated for any grade level by just changing
the number and types of clues. Consider making number talks a part of your routines at home!
Guess My Number
What to do:
1. Let your child think of a number between a stated range of numbers while you try to guess the number by
asking questions. Here is a sample conversation.
Child: I am thinking of a number between 1 and 100.
Parent: Is it more than 50?
Child: No.
Parent: Is it an even number?
Child: No.
Parent: Is it more than 20 but less than 40?
Child: Yes.
Parent: Can you reach it by starting at zero and counting by 3’s?
Child: Yes.
(At this stage, your child could be thinking of 21, 27, 33, or 39.)
2. Figure out the answers to your own questions.
3. After you have guessed your child’s number, let your child guess a number from you by asking similar
questions.
*Some math vocabulary ideas for questions: even, odd, divisible by, a multiple of, greater than, less than, naming a
digit in tens, ones, hundreds, etc. place, prime number, composite number, square number.
