What Each Text Adds is a free printable Grade 3 English worksheet on finding what one text gives that the other does not, aligned to Common Core standard RI.3.9. It prints 2 questions with an answer key on its own sheet of paper, in 25 versions, 23 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. 23 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. Which is easier to send across a distance, and why?
  2. 2. How is Morse code like braille?

How Braille Was Invented

Louis Braille was blinded in an accident at the age of three. At his school, blind pupils read by tracing raised letters pressed into paper. It worked, slowly — a fingertip cannot take in a whole letter shape at once — and nobody could write that way at all. When Braille was twelve, a soldier visited the school with a code of raised dots that soldiers used to read messages in the dark. It was too complicated, but the idea of dots was right. Braille spent three years simplifying it. He settled on a cell of six dots, small enough to sit under one fingertip. He was fifteen when he finished. He was forty-three when he died, and the system was not widely accepted until after that.

  2. 2. How is braille different from Morse code?

Answer key — What Each Text Adds

Set 11. Prints on its own sheet.

  1. 1.1. Morse — it can be sent as sound or light, while braille has to be touched. 2. Both were designed so a message could be read without ordinary print.
  2. 2.1. Both replace letters with a simple pattern that can be sent or read another way. 2. Braille is felt with a fingertip and can be written by the reader; Morse is heard or seen in time.
