Where, When, Why and How is a free printable Grade 3 English worksheet on using text and image to answer across an event, aligned to Common Core standard RI.3.7. It prints 2 questions with an answer key on its own sheet of paper, in 25 versions, 24 of them with different questions, so no two pupils in the class work from the same page. Print it from the browser or download it as a PDF — no account, no email.

Set 1 has all 25 in a single PDF. 24 of these 25 sets ask different questions — this skill does not have 25 questions to give. The rest reorder them, so no two pupils have the same paper in front of them.

Morse Code

Morse code turns every letter into a pattern of short and long signals: dots and dashes. The commonest letters were given the shortest patterns. E is one dot. T is one dash. Q, which is rare, is dash-dash-dot-dash. Because of that choice, an average message is much shorter than it would be otherwise. A message can be sent as sound, as light, or as taps on a pipe. That is why it survived so long: it needs almost no equipment. Timing carries the meaning. A dash is three times as long as a dot. The gap between letters is three dots long, and between words, seven. SOS was chosen because it is easy to recognise: three dots, three dashes, three dots.

  1. 1. In a message, which gap is longer: between letters or between words?
  2. 2. What would a diagram of a Morse message need to show?

How a Windmill Grinds Flour

A windmill turns moving air into turning stone. The sails are set at a slight angle. Because of that angle, wind pushing on them cannot pass straight through, so it pushes them round instead. The sails turn a horizontal shaft. A large wooden gear on that shaft meshes with a smaller one on an upright shaft, which turns the millstones below. Because the smaller gear has fewer teeth, it spins faster than the sails do. Four turns of the sails can mean twenty turns of the stone. The grain falls between two stones. The top stone turns; the bottom one does not. The grain is crushed between them, and flour comes out at the edge.

  1. 1. Put these in order: the millstones turn, the sails turn, the gears mesh.
  2. 2. What would a diagram of a windmill need to label?
