value of the number just imagine if one adds or even removes a zero from their salary. Index Terms— Zero, Mesopotamia, Mayan, Brahmagupta, Al-Khwarizmi, Fibonacci, Descartes. I. Introduction…
dark ages were not really a time of darkness. There were great advancements and inventions during that time. During the Medieval Times, there were many advances in agriculture, science and architecture. Some of the advances include the change of the number system, the change of animals in which they used to farm and the gothic architecture used during this time. There were many advances in agriculture during the middle ages. Many peasants farmed the land with different grains such as wheat,…
360 was used for circles The Sumerians also gave us the decimal system. The Hindu’s gave us the Arabic Numeral System which gave mankind counting numbers. With the extension of numbers, math took off. The Hebrew’s gave us another numeral system but this one went into the hundreds. The Babylonians gave us the digit 0 and then we had a a completed number system for that time. Agriculture was a ginormous element when civilization was first coming together and it has stuck with humans all through…
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…
2014 pp. 90 identifies that a major cause of student’s difficulties in mathematics has been how they understand and process numbers. The teacher then writes on the board 723- 246. The class is asked to copy and complete the above exercise in their books. The teacher then asked a student the answer. The student says “four hundred and seventy-seven”. The teacher interrupts the student:…

Once completed, you will submit this document to WGU for grading. Instruct What student misconceptions have you encountered related to fraction, decimal, and percentage concepts? How do you help students understand the notion of equivalence among fractions or prepare them for this understanding? One…
student will start to develop their place value knowledge once they are confident using number names, classifying objects, identifying patterns and as they begin to develop their counting skills. From Year 1, the Australian Curriculum expects students to count collections to 100 by partitioning numbers using place value (ACARA, 2016). This means students need to learn about grouping in tens and that two-digit numbers are made up of tens and ones. Booker, Bond, Barrow and Swan (2014, p. 87)…
entry-level mathematics students often encounter difficulties in understanding magnitudes of large numbers. I shall begin my case study from some experiments that how accurately the children could estimate the numbers magnitudes by various aspects of a stimulus. Thus far, my research has followed two lines of inquiry. The first line of study is to identify children’s different understanding levels for number magnitudes and to accurately estimate numbers7. Specifically I am interested in…
Classify objects into given categories; count the number of objects in each category and sort the categories by count. K.CC.4a. When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object. K.CC.6. Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using…
children are likely to be helpful/unhelpful in scaffolding their thinking (Bottle, 2005). Drews (2007) also noted that whilst structured manipulatives, such as, Dienes and Cuisenaire are especially helpful for children struggling with decomposition and number property and relationships, unstructured manipulatives such as Multilink, counting materials or collections of shapes are more versatile and encourage children’s own application. The ability to use manipulatives in diverse ways encourages…
