There are two sounds for th. In think, three, thank and bath, the tongue is between the teeth and we blow air. There is no buzz. In this, that, these, mother and brother, the tongue is in the same place but we make a buzz in the throat. Next, two word endings. The ending -ous makes dangerous, famous and enormous. The ending -ive makes creative, expensive and active. Last, triangles. A triangle is a flat shape with three sides. In an equilateral triangle, all three sides are the same length. In an isosceles triangle, two sides are the same length. In a scalene triangle, every side is different. A right-angled triangle has one square corner. Each side of the Pyramids of Giza is a triangle.

|---|---|
| equilateral | 3 equal sides |
| isosceles | 2 equal sides |
| scalene | no equal sides |
Triangle hunt. Look for triangles at home or outside: a roof, a sail, a slice of bread cut across, the sides of a pyramid. Say what you see: This is a triangle. It has three sides. Then draw one equilateral, one isosceles and one scalene triangle with a ruler and count equal sides.
