1 Sometimes, always, never? 1. If you multiply an even number by 5, the answer is a multiple of 10. 2. A hexagon has no lines of symmetry. 3. If you fold a square in half, you get two triangles. 4. An even number divided by an even number equals an even number. 5. Multiplying gives a higher answer than the number you started with.

2 Sometimes, always, never? 1. If you add a 2 digit number to a 3 digit number, you get a 3 digit answer. 2. Polygons have equal sides. 3. An odd number multiplied by an odd number equals an odd number. 4. Square numbers cannot be prime numbers. 5. A fraction is smaller than a whole.

3 Sometimes, always, never? 1. A circle has infinite lines of symmetry. 2. All lines drawn on a circle will be lines of symmetry. 3. A circle has no rotational symmetry. 4. A quadrilateral has 2 lines of symmetry. 5. Number of edges = order of rotational symmetry.

4 Sometimes, always, never? 1. Whole numbers divided by 2 give whole number answers. 2. Adding to a number always gives a higher value answer. 3. The method for finding the area of a rectangle can also be used to find the area of other parallelograms. 4. Half of any positive integer will always be greater than zero.

5 Sometimes, always, never? 1. Any number times 0 equals 0. 2. Any number times 1 equals 1. 3. Any number times 10 will end in a zero. 4. Any number times 5 will end in a zero. 5. Any number times 0.5 will equal half of itself.

6 Sometimes, always, never? 1. Perpendicular lines are not parallel. 2. multiplying a 3-digit number by a 2-digit number gives you a 6- digit answer. 3. Triangles don’t have obtuse angles. 4. A shape with line symmetry also has rotational symmetry.

7 Sometimes, always, never? 1. If you multiply a whole number by 10 it will end in zero. 2. If you divide a whole number by ten it will end in zero. 3. If you fold a square in half, you get two triangles. 4. If you add two 3 digit numbers you will get a 4 digit answer. 5. A circle has no lines of symmetry
