• ## Diagnostic Assessment

Boris is confident in their 2’s, 3’s, 4’s and 5’s skip counting, however they are not experienced in anything above 5’s. The butterflies were different colours and not standard dots or squares, they were also misarranged, which caused some hesitation until I showed Boris how to mentally and physically (with a finger on each, or imagining groups of) reposition them or to regroup. Pony calls and Partitioning of numbers was another…

• ## Simon Stevin's Life And Accomplishments

worked to fix concepts that were already founded by many other mathematicians. Although he did some amazing things for mathematics he was also known for his work in science, and engineering. He did things such as inventing a carriage, standardizing decimal fractions and their uses, as well as refuting the doctrine created by Aristotle that stated, that heavy bodies fall faster than lighter ones, and list of the things he's done continues. Simon Stevin, was born illegitimately sometime in…

• ## Pt1420 Unit 3 Assignment 1 Data Type Analysis

up to a definite amount. It holds up to 7 digits. • Shouldn’t be used for currency as the decimals will represent a lower number and it isn’t exactly a big number. • Used as a number up to 7 digits. If the number does not have 7 digits, it will be rounded to have a format of 7 digits. An example is with the value 1.23456789. As you can see, it exceeds 7 digits and so is rounded to 1.234568. • Used for decimals as the pre-set value. Double An 8 data type which can hold 14 digits compared to a…

• ## Significant Figures

calculation. When taking significant figures into account for a problem, exact numbers will not affect them either. When performing a measurement on a digital instrument, read and record all of the numbers as displayed, including zeros after the decimal point. But on a scaled instrument, estimate one more figure than you can actually read from the scale. This accounts for the inaccuracies and errors that occur naturally. Accuracy is “a measure of the deviation of the measured value from the…

• ## Positive And Effective Learning Environment Analysis

The focus area I have chosen for this inquiry is to create a supportive and productive learning environment that is safe and fun for my students to develop their mathematical thinking and reasoning. This is based, in part, on my teaching philosophy (Figure 1). A personal goal of my teaching placement is to adopt teaching practices that can offer my students a safe, morally-affective, positive and inclusive learning environment, where they can be fostered and encouraged to freely and actively…

• ## Leibniz's Number System

Computers have all but replaced humans for doing complex calculations. But computers handle numbers much differently than humans do. At this point, the majority of people use base-10 for their math. The base of a number system refers to the number of number symbols used in that system. In base 10 the numbers used are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Humans use this system because it shortens numbers. Humans have 10 fingers so it is logical that base-10 counting systems developed naturally. But…

• ## Math Misconceptions

various new math ideas are presented and many students can face difficulties when new material is introduced. Difficulties are especially displayed when it comes 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…
