Question
While developing students' understanding of the relationships for numbers 10 through 20, all of the following should be kept in mind EXCEPTa) Even though students experience numbers up to 20 regularly in real life, it should not be assumed that they will automatically extend the relationships they learned for numbers 1 to 10 to bigger numbers.
b) These relationships are just as important as the ones involving numbers 1 to 10.
c) Children should learn that there is a set of ten involved in any number between 10 and 20.
d) While learning about these relationships, students should develop a complete understanding of the concept of place value.

Q:
Which is NOT an illustration of the relationships between the various area formulas?
a) A rectangle can be cut along a diagonal line and rearranged to form a non-rectangular parallelogram. Therefore the two shapes have the same formula.
b) A rectangle can be cut in half to produce two congruent triangles. Therefore, the formula for a triangle is like that for a rectangle, but the product of the base length and height must be cut in half.
c) The area of a shape made up of several polygons (a compound figure) is found by adding the sum of the areas of each polygon.
d) Two congruent trapezoids placed together always form a parallelogram with the same height and a base that has a length equal to the sum of the trapezoid bases. Therefore, the area of a trapezoid is equal to half the area of that giant parallelogram, 1/2h(b1+b2).
