double-digit addition problems (place value, empty number line, break apart). Ask student, “Do you think we could use some of these same strategies to find the sum of three-digit numbers?” “Today, we are going to use those same strategies to solve three-digit addition problems.” 2. Objective/EQ: During math today, we are going to play a game that includes adding two three-digit numbers using the place value strategy (includes base ten blocks), the empty number line strategy, or the break apart…
Find out the numbers that has the greatest value a) 5.3 b) 4.99 c) 5.198 d) 5.04896 Children should have the ability to compare, order ad represent decimals (11, ACMNA105). The correct answer for the above question is 5.3. Some of the misconceptions could be: some students may choose 4.99, with the misconception that 99 is the highest number, without considering the whole number, in which 4 is less than 5. Students may rule out 4.99, compare the other three numbers, and choose 5…
to discovering decimals. Although decimals are introduced in fourth grade they are continuously presented in math thereafter. One common misconception held about decimals is the idea that the more digits that are presented in a number, the greater the value of the number. An example of this is students believing that 3 is less than 0.7648 when this is definitely not the case. This misconception is related to Mariam Small’s third big idea where it is stated that by something about mathematical…
Part B Diagnostic Assessment During the diagnostic assessment which focused on grade three student, Boris’s comprehension of number placement and value, Boris did well in most areas, with minimal exceptions. Boris took a great deal of time, when requested to partition the double digit the number. Though they progressed to partitioning the larger numbers in a standard and acceptable non-standard manner, they answered the two digit partitioning question with various multiplication equations.…
possible 334 points. The teacher will divide the number of points earned, 299, by the total possible points, 334, with the answer of 0.895. The teacher then multiplied this answer by 100 creating the number 89.5. This number is able to be rounded to the nearest ten percent, 90%. The student achieved the qualification for a grade of A. The student would not be given the grade of A if the teacher truncates the whole number. Truncating the number to the nearest whole, would leave the student…
the list goes on. I had a notebook in the third grade in which I would write numbers from one and beyond. Unfortunately that list was never finished; the fact that one could begin to write numbers from the day they were born to the day they would die and would not even be close to infinity is both scary and fascinating to me. This blew my eight year old mind. It sparked this passion in me to expand my knowledge of numbers, how they work and why they worked. Now I’m engaged in Calculus trying to…
of all numbers: The dictionary meaning of prime is ‘Of first importance’ or ‘Of the best quality, excellent’ etc. What is so great about prime numbers? A number is said to be a prime if it is divisible only by 1 and itself. 5, for example, is a prime number because it is divisible only by 1 and 5. The number 4 can be divided by 1, 4 AND 2. So it is not a prime number. Numbers that are not primes are said to be composite numbers. The fundamental theorem of Arithmetic states that all numbers are…
The formula is written like this, (a + 1)(b + 1)….(z + 1) where a, b, …., z are considered to be the exponents of prime number. So looking at 225 we know that it has prime numbers 2 and 5 with a exponent of 2 next to the 2. So using our formula we will now use (2 + 1)(1 + 1) = (3)(2) = 6. Now when we’re looking at this there are many different possibilities of factors of 20. When looking at the term…
Sam Kean, a Washington D.C. writer with works in The New York Times Magazine, Mental Floss, Slate, The Believer, Air & Space, Science, and The New Scientist, has created a user-friendly book about how to explain the periodic table and the elements that occupy it by writing the book The Disappearing Spoon: And Other True Tales of Madness, Love and the History of the World From the Periodic Table of Elements. He provides an insight into the world of chemistry that relates to his audience, even…
If a problem is worth 2 points and you only show the answer, then you will receive only 1 point credit. If you use a calculator or online website, give the source and tell me exactly what you provided as input. For example, if you used Excel to compute 16 * 16, state “I typed =16*16 into Excel and got 256. You may type your answer right into this document. Part I. Basic Computations 1. According to the National Education Association , the average classroom teacher in the US…
