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.

Turning Milk into Cheese

Cheese begins as an accident that people learned to repeat. Milk is mostly water with fat and protein in it. To make cheese, the protein has to be separated out. A starter culture of bacteria is added first. The bacteria turn some of the milk sugar into acid, and the acid begins to make the protein clump together. Then rennet is added, which finishes the job. The milk splits into solid curds and watery whey. The whey is drained off. The curds are pressed, salted, and left to age. Time does the rest: a cheese aged for two years tastes nothing like the same cheese at two weeks.

  1. 1. How is cheesemaking like breadmaking?
  2. 2. How is cheesemaking different from breadmaking?

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. How is Morse code like braille?
  2. 2. Which is easier to send across a distance, and why?

Answer key — What Each Text Adds

Set 14. Prints on its own sheet.

  1. 1.1. Both use living things — bacteria or yeast — to change a food, then set the result. 2. Cheese is made by separating and pressing; bread is made by trapping gas and baking.
  2. 2.1. Both were designed so a message could be read without ordinary print. 2. Morse — it can be sent as sound or light, while braille has to be touched.
