Presentation on theme: "Sometimes, always, never?"— Presentation transcript:
1Sometimes, always, never? If you multiply an even number by 5, the answer is a multiple of 10.A hexagon has no lines of symmetry.If you fold a square in half, you get two triangles.An even number divided by an even number equals an even number.Multiplying gives a higher answer than the number you started with.
2Sometimes, always, never? If you add a 2 digit number to a 3 digit number, you get a 3 digit answer.Polygons have equal sides.An odd number multiplied by an odd number equals an odd number.Square numbers cannot be prime numbers.A fraction is smaller than a whole.
3Sometimes, always, never? A circle has infinite lines of symmetry.All lines drawn on a circle will be lines of symmetry.A circle has no rotational symmetry.A quadrilateral has 2 lines of symmetry.Number of edges = order of rotational symmetry.
4Sometimes, always, never? Whole numbers divided by 2 give whole number answers.Adding to a number always gives a higher value answer.The method for finding the area of a rectangle can also be used to find the area of other parallelograms.Half of any positive integer will always be greater than zero.
5Sometimes, always, never? Any number times 0 equals 0.Any number times 1 equals 1.Any number times 10 will end in a zero.Any number times 5 will end in a zero.Any number times 0.5 will equal half of itself.
6Sometimes, always, never? Perpendicular lines are not parallel.multiplying a 3-digit number by a 2-digit number gives you a 6-digit answer.Triangles don’t have obtuse angles.A shape with line symmetry also has rotational symmetry.
7Sometimes, always, never? If you multiply a whole number by 10 it will end in zero.If you divide a whole number by ten it will end in zero.If you fold a square in half, you get two triangles.If you add two 3 digit numbers you will get a 4 digit answer.A circle has no lines of symmetry
