Abundant number

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…

their bodies. Silicon is an element a pure substance that can’t be broken down. Silicon was first discovered in 1824 by a Swedish chemist named Jons Jacob Berzelius. This element is the second most abundant and it makes up about 27.7% of the earth’s crust. Although silicon is the second most abundant element, and it can’t be found free in nature. Silicon is usually found as silica or silicates. In order to obtain silicon by itself sand or carbon needs to be heated. In the next paragraphs, I…

This implies many things. The atomic number of an element indicates how many electrons and protons there are. The number of electrons should always be the same of protons because their charges cancel and the overall charge of the atom is neutral, and so the number of protons and electrons of copper is 29. There are 29 electrons surrounding the nucleus, organized in orbitals. There are 29 protons in the nucleus, however the number of neutrons is dependent of the carbon isotope being…

The atomic number for Neon is 10, keeping in mind that the atomic number is the number of protons in an element. The atomic mass of Neon is 20.180, which when rounded up will become an atomic mass of 20. The state of matter Neon is mainly in is a gaseous state. The full electron configuration of neon…

does not yet show to have a limit to the number of individuals in their population. Of course, there is a carrying capacity for these type of birds, as well, but this sample does not show to be large enough to exceed their limit. Since the graph shows a general upward trend, it can be concluded…

The element Titanium is a very light metal and it’s in the periodic table group 4. This element is a transition metal and the symbol is Ti. The color of titanium is a silver grey and white color. The atomic mass is 47.867 and atomic number is 22. This element however is resistant to chlorine, and sea water. It has 22 electrons, 22 protons, and 26 neutrons. The density is 4.54 The discoverer who found titanium is William Gregor a Mineralogist. The year it was discovered was in 1791. Where it had…

Holmium is a brilliant dim metal found in the lanthanide section on the periodic table, which is for the most part appeared at the bottom of the periodic table. This element has 67 protons in its nucleus, which implies it is the 67th component on the periodic table. Holmium is pliable, which infers it can be bowed and folded. It is the foremost magnetic component of the periodic table. The name comes from the element lanthanum. The lanthanides are also known as rare earth elements. Although…

atom is the proton. The proton is a very important part of an atom, because the atomic number of an atom is equivalent to the number of protons that that atom has. Additionally, the mass of an atom is equal to the sum of the number of protons and the number of neutrons of that atom. The number of electrons that an atom has is also equal to the number of protons that that atom has.…

mineral petalite (Jefferson Lab Web). However, even though this element was found by Arfvedson, William Thomas Brande and Sir Humphrey Davy were the first people to isolate it (Jefferson Lab Web). Lithium is very abundant, it is a soft silver white alkali metal with the atomic number of three. Lithium is silver and contains no odor (Element Project). In addition to those features, lithium has a total of seven isotopes, two natural and five unnatural. The two natural occurring isotopes are…
