Literacy Activities
Introduce target words

• Display a list of target words that end in er.
• Read the words with the children.
• Read A Spider Gets Wider and Wider target text (see below) with the children and have them underline words that end in -er.

Watch a spider get  wider

• Draw a picture of a spider on a balloon.
• Blow up the balloon little by little and show how the spider gets wider and wider. 
• Have the children write “The spider gets wider and wider.”

Watch the spider be a rider

• Read A Spider Can Be a Rider (see below) and have the children act out the text using the following prompts:
  • Rider: Hold the string for the spider and make the spider ride a child's shoulder. 
  • Flyer or glider: Make the spider glide through the air.
  • Slider: Make the spider slide along the ground or slide down a child’s arm or leg.
  • Strider or walker: Make the spider walk or stride along a piece of paper.

Identify and make words with -er

• Write words that end in -er for the children to see (e.g., spider, wider, strider, glider, slider, rider, ripper creeper; slipper, snapper, fatter, patter, splatter, matter, faker, maker, striker, and strider).
• Have the children put word-building cards together (see below) to recreate words ending in er (e.g., fa + ker → faker and pat + ter → patter).
