FORMATIVE ASSESSMENT 

Students complete the “Picture This” Activity to create a visual description of digestion using key vocabulary and important information from the text. The teacher models this on an overhead for students and help students determine four phases of digestion. A detailed example has been included.

 

LEARNING ACTIVITIES

 

  1. Develop new vocabulary words dealing with digestion using a Rivet Activity. Words to decode and solve include: digest, chew, saliva, swallow, esophagus, stomach, intestines, and blood.

 

Strategy

Rivet

  • Prepare a list of six to eight important words.
  • Number the words and draw blanks on the board or overhead to indicate how many letters each word has. Students may reproduce this on a piece of paper.
  • Fill in the initial letter for the first word. Have the students do the same on their paper.
  • Encourage students to make a guess based on what they see.
  • Gradually add the other letters to the word. Continue to encourage guesses as each letter is added.
  • Once most of the class has agreed on the correct word, ask them to help you finish spelling the word correctly on the board and on student papers.
  • Start at step one for the next word. When all words are completed have students make predictions about the information or events that will occur in the selection.
