Add a Visual Display is a free printable Grade 3 English worksheet on choosing where a visual would emphasise a detail, aligned to Common Core standard SL.3.5. 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 6 of 25 · the same problems every time you open this link.

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. What would a diagram of a Morse message need to show?
  2. 2. How would a table help a reader of this text?

How a Canal Lock Works

A canal cannot run uphill. Where the land rises, engineers build a lock: a chamber with a gate at each end. A boat going uphill enters the lock through the lower gate. The gate closes behind it. Sluices in the upper gate are opened. Water flows in from the higher stretch of canal, and the boat rises with it. No pump is needed, because the water comes down by gravity. When the water inside matches the level above, the upper gate can be opened and the boat moves on. Going downhill, everything runs the other way: the water is let out, and the boat sinks with it.

  1. 1. What would a diagram of a lock need to label?
  2. 2. How would a labelled diagram help a reader of this text?

Answer key — Add a Visual Display

Set 6. Prints on its own sheet.

  1. 1.1. The dots, the dashes, and the different gap lengths between letters and words. 2. A table of letters against their dot-and-dash patterns would let a reader look one up.
  2. 2.1. The lower gate, the upper gate, the sluices, the chamber and the two water levels. 2. It could show both gates, the sluices and the two water levels at once, which words have to take in turn.
