ch 14 lesson 1-11

 
need a one week long math lesson plan using the five e’s format from prince george’s county maryland public schools. I will upload chapter two of the my math series. need to combine lesson 14-1, 14-2, 14-3, 14-4, 14-5, 14-6, 14-7,14-8, 14-9,14-10,14-11 . for grade 4 please make sure you use the 5 e format make sure there are 5 phase one – engagement make sure there are 5 phase five – evaluate Think of each activity in each E of the plan and how much time you give for each. Not necessarily 5 for exploration bc it could take 3 or 4 to days to complete, exploration can be centers, a project, big problems or a scavenger hunt in which students will take longer to do (2 days). The teacher during elaboration brings the knowledge back from students to the teacher so the teacher can connect and correct any knowledge or misunderstanding, teach rules, procedures etc. Also, keep in mind that students must read, speak and write during the math block. Time for that is needed as well. If you include 2 or 3 ‘meaty’ activities within the lesson plus warm ups and homework, you’ll b fine! Your lesson plan can last at least 4 – 5 days. Hope this helps please make sure you use the 5 e format make sure there are 5 phase one – engagement make sure there are 5 phase five – evaluate Think of each activity in each E of the plan and how much time you give for each.

Hope this helps, also include fluency activities-(basic facts), vocabulary development (interactive notebook activity and on Friday you can do review activities and then a big quiz. follow chapter 10 as an example make sure there are four group rotation. Also new I need questions for higher order thinking. Using the DOK levels. I need questions that are level three and four.

You are being asked to create graphs and perform calculations. Make sure that you label all
graphs properly. Both the X and Y axis should be labelled. There should be a legend showing
each series on the graph. In short, someone who hasn’t read the questions should be able to
understand what is shown in your graphs. Be sure to show your work for the calculations.
You should write down the general formula and the specific numbers that you are using to
reach your answer. You will lose marks if we cannot see how you reached your answers,
even if your final answer is ultimately correct
Format: The first page must give the project title, your name, your student number, and
a word count. The project essay should be no more than 2,000 words long. Any words
beyond 2,000 will not be read; only the first 2,000 words will be assessed. The words on the
title page and in the bibliography do not count towards the word limits. You must reference
all sources (including the assigned articles) and you must include a separate bibliography.

Hungarian Solution Method
1) Perform row reduction by subtracting the
minimum value from all entries in the same row;
2) Perform column reduction by subtracting the
minimum value from all entries in the same
column;
3) Cross out all zeros with a minimum number of
horizontal/vertical lines;
4) If the number of lines is equal to the number
of rows/columns this is the optimal solution ,
otherwise subtract the minimum value from
uncrossed values from all uncrossed values and
add this value to the intersection values;
5) Go to step 3

The Impact of Numbers on Contingent Valuation

 
I want to have a reaction paper were the opinions are strongly supported by evidence. The reaction paper should be based on whether you agree,disagree, or an open ended opinion on a statement in the paper.
The paper should start with two to three sentences introduction on the topic addressed. Then an opinion on whether a statement in the paper is agreed/ disagreed on.
Finally, a conclusion should end the paper.

BTM week 6

1. Calculate the sample size needed given these factors:
• one-tailed t-test with two independent groups of equal size
• small effect size (see Piasta, S.B., & Justice, L.M., 2010)
• alpha =.05
• beta = .2
• Assume that the result is a sample size beyond what you can obtain. Use the compromise function to compute alpha and beta for a sample half the size. Indicate the resulting alpha and beta. Present an argument that your study is worth doing with the smaller sample.
2. Calculate the sample size needed given these factors:
• ANOVA (fixed effects, omnibus, one-way)
• small effect size
• alpha =.05
• beta = .2
• 3 groups
• Assume that the result is a sample size beyond what you can obtain. Use the compromise function to compute alpha and beta for a sample approximately half the size. Give your rationale for your selected beta/alpha ratio. Indicate the resulting alpha and beta. Give an argument that your study is worth doing with the smaller sample.
3. In a few sentences, describe two designs that can address your research question. The designs must involve two different statistical analyses. For each design, specify and justify each of the four factors and calculate the estimated sample size you’ll need. Give reasons for any parameters you need to specify for G*Power.

Include peer-reviewed journal articles as needed to support your responses to Part 1 above.

Support your paper with a minimum of 5 resources. In addition to these specified resources, other appropriate scholarly resources, including older articles, may be included.
Length: 5-7 pages not including title and reference pages
References: Minimum of 5 scholarly resources.
