Hello Year 5,
This half term’s Maths Challenge links to our Rivers topic.
Bronze
The River Nile is 4132 miles long – round to the nearest 1000, 100 and 10.
Where are the coldest waters in the world? Find the location of the coldest waters around the world and identify the average temperature. Put the waters in descending order. Remember to label and explain.
Silver
Research the temperature of the Pacific Ocean and calculate the temperature differences of this throughout the year e.g. the maximum and minimum temperatures.
Locate the 3 deepest oceans and calculate the combined depth of these in metres and km.
Then order these oceans by the depth and then by temperature too.
Gold
The Atlantic Ocean covers approximately 106,400,000 square kilometres which is 20% of the Earth’s surface. How many square kilometres is the Earth’s surface?
How many square kilometres is the surface of the earth covered by land? What percentage is this?
Can you order the oceans by square kilometres too?
Good luck Year 5 – Complete your work in your homework books.
