Using Trigonometry
Fifth graders explore the use of trigonometry to find unknown sides and angles in right-angled triangles, taking the concepts that were developed in the previous unit and looking at different ways of practicing the new skills. Students...
Curated OER
Measurement
Young scholars use arithmetic in a practical situation using time and distance.
As the calculations involved in this problem involve single digit addition and multiplication it offers a good opportunity to encourage the students's use...
Curated OER
World-wide Search for the Dominant Trait
Students receive instruction on dominant/recessive traits, access World-Wide Search for the Dominant Trait and download information on which traits to assess. They collect data on at least 20 people and prepare a data chart.
Curated OER
Pay Check Advance Loans
Students explore the implications of obtaining loans. They assess interest rates, amount to be paid back, and the implications if they do not pay back the loan on time. Students develop a comparison chart.
Curated OER
The Box with the Greatest Volume
Students use measurement tools to measure the nearest 16th of an inch. They connect fractions and their decimal equivalents and compare this with other decimals. Finally, the class uses algebraic concepts and formulas to solve problems.
