Can I compute surface area and volume of composite 3-D geometric figures, given geometric formulas. Difficult crossings problems are exemplified by the dilemma of three couples trying to cross a stream in a boat that will hold only two persons, with each husband too jealous to leave his wife in the company of either of the other men.

I have come up with an arrangement that gives area 0.

Can I determine absolute values or rational numbers on a number line. Which weights should you bring. The lockers that are exact squares will remain open. The student is expected to recite numbers up to at least by ones and tens beginning with any given number.

By the end of year 6, pupils should be fluent in written methods for all 4 operations, including long multiplication and division, and in working with fractions, decimals and percentages. The student applies mathematical processes to understand that exponential and logarithmic functions can be used to model situations and solve problems.

For those of you who are old enough to remember, this is the Let's Make A Deal problem. A spider sits at one corner of a cube. The second student closes the even numbered lockers. Achieving three in a row constitutes a win. Pain the origin red, and designate 2 points orange and yellow on the unit circle, forming an equilateral triangle.

Using patterns to identify geometric properties, students will apply theorems about circles to determine relationships between special segments and angles in circles. The student uses the process skills in applying similarity to solve problems. Pupils use both analogue and digital hour clocks and record their times.

Can I write an equation of a line passing through two given distinct points. The next day, Thursday, you climb back down the hill. Students develop a variety of strategies to use efficient, accurate, and generalizable methods to add and subtract multi-digit whole numbers.

Among the outstanding problems given by Bachet were questions involving number bases other than 10; card tricks; watch-dial puzzles depending on numbering schemes; the determination of the smallest set of weights that would enable one to weigh any integral number of pounds from one pound to 40, inclusive; and difficult crossings or ferry problems.

Can I use the Pythagorean Theorem to determine unknown side lengths in a right triangle. The power consumed, and hence the work done by the generator, is proportional to the voltage squared. In the beginning, the rock caused the water level to rise by an amount that exactly compensates for the weight of the rock.

To find the perimeter of any shape add all lengths and widths together. In fact, by similar reasoning, the curve can be made to fill completely an entire cube. On each side the sum of the first powers S1 is 22 and of the second powers S2 is Among British contributors, Henry Dudeneya contributor to the Strand Magazine, published several very popular collections of puzzles that have been reprinted from time to time — Will it eventually fall into a pocket, or can it bounce around the table forever.

But if the rules are extended, many additional combinations are possible. The first number in the list might be 0. As students share I will write an expression on the board to represent the perimeter of each shape.
