Year 7 Interpreting Graphs and Maps — Step‑by‑Step Answers & How to Complete (Student age 16)

Quick note before we start

I can give exact answers only if you provide the missing tally numbers or a picture of the table/graph and the map. Below I explain, step by step, how to complete each part and I give the parts I can fill in now (world countries, capital table). If you upload the table/graph image or type the tallies, I will fill in every blank exactly.

PART A — Complete the totals and draw the bar graph

What you need to do:

1. Look at the "Number of students (tally)" column in your table. Convert each tally to a number. (Example: |||| = 4, ||||/ with a diagonal through the four = 5, etc.) Write that number in the "Total" column next to each island/country.
2. Sum all totals to get the total number of Year 7 students altogether.
3. To draw the bar graph:
1. Title: write a clear title, for example: "Number of Year 7 Students by Island/Country".
2. X‑axis: list the islands/countries (Malekula, Pentecost, Australia, Tanna, Tongoa, Epi, Banks, China). Label the axis "Island / Country".
3. Y‑axis: number of students. Choose a scale that includes the highest value (for example 0, 2, 4, 6, 8, 10). Label the axis "Number of students".
4. Draw one vertical bar for each island using a different colour for each bar (you can use coloured pencils or pens). The bar height equals the total number of students for that island.
5. Include a key if you want, but if each bar is labelled with the island name on the x‑axis a key is optional.

If you send me the tallies I will convert them and draw (or describe precisely) the bar heights for you.

PART B — Answering the questions from the completed graph

How to answer each question once your graph is complete — replace my examples with your numbers:

• How many students are from Malekula?
  Read the height of the Malekula bar or the total you wrote in the table. Write that number.
• Which islands have an equal number of students in this school?
  Look for bars of the same height (or identical totals in the table). List the two islands that match.
• Which island has the most students in this school?
  Find the highest bar (largest total) and write the island name.
• How many students are from the Shefa province?
  Add totals for islands that belong to Shefa province (you need to know which islands in your list are in Shefa — e.g., Epi and Tongoa are in Shefa; verify using your map). Write the sum.
• How many students are from the Tafea province?
  Add totals for islands in Tafea (e.g., Tanna is in Tafea). Write the sum.
• Which island has the least number of students?
  Find the smallest bar / smallest total and write the island name.
• How many students are from other countries?
  Add totals for non‑Vanuatu countries in the list (e.g., Australia and China). Write that sum.
• How many Year 7 students are there altogether?
  Add every island/country total to get the grand total.

If you give the tallies I will compute every numeric answer and show working.

MAP TASKS — Label provinces and mark South

What you must do on the map sheet:

1. Use a pencil to draw province boundaries so the islands are grouped into six provinces (Torba, Sanma, Penama, Malampa, Shefa, Tafea). Look up a reference map of Vanuatu if you need help placing the province boundaries.
2. On every copy of the map write the letter "S" on the side that is south (the bottom of the map unless the map is rotated). This shows where south is.
3. Name the islands indicated by the lines on your map. If you send me a photo or name them here I will confirm the island names.

Draw a cross section of an island (how to)

1. Place your ruler (frame) across the map where the line for the cross section is drawn (for example from point A to point B).
2. Along the line, mark every contour line where it crosses. Next to each mark write the elevation of that contour (e.g., 50 m, 100 m) taken from the map's contour labels.
3. On graph paper or the cross‑section frame, draw a horizontal baseline representing the ground line. Plot the elevations at the correct distances along the baseline. Then connect the points smoothly to form the island shape (mountain / slope / valley). This is the cross section.

Matching cross sections to maps — method

To match each small map to one of the cross‑sections:

1. Look at the contour patterns on the map: where contours are close together there is a steep slope, where contours are far apart the slope is gentle.
2. Examine the cross section shapes: a sharp point or steep sides means the map should show closely spaced contours; a wide rounded hill means contours are widely spaced.
3. Also look for features such as two peaks, a valley, or asymmetry — match these to the cross‑section shape. Label each cross section with the matching map.

Contour line rules — answers

• When there is a steep slope contour lines are: close together.
• When there is a gentle slope contour lines are: far apart (widely spaced).
• There are no contour lines when the land is: completely flat (or at a single elevation across the area, e.g., a flat plain or sea level).

Five largest countries in the world (by area) — answers

1. Russia with an area of 17,098,242 km²
2. Canada with an area of 9,984,670 km²
3. United States of America with an area of 9,826,675 km²
4. China with an area of 9,706,961 km²
5. Brazil with an area of 8,514,877 km²

Continent / Country / Capital table — completed

Here are the filled rows for the table you provided:

What I still need from you to give full, exact answers

• A clear photo or the exact tallies for the table (the tally marks column) so I can convert them to totals and compute every graph question.
• A photo of the map (or the names of the islands indicated by lines) and the maps used for matching cross sections so I can match each cross section to the correct map and give the cross‑section drawings.

If you want — example of how I will respond after you send tallies

Send the tallies (for example: Malekula ||||/ = 5, Pentecost |||| = 4, Australia ||||/ || = 7, etc.). I will:

1. Write the completed totals table.
2. Draw and label the bar graph (I will describe exact bar heights and axis scale or produce a simple image if you want).
3. Answer every question in Part B with numbers and show the addition for province totals and grand total.
4. Match cross sections to maps if you send the small maps and cross‑section images.

Send the tallies and map images now and I will finish every blank for you.
