Yuck Kingdom Lesson Plans


Jeff Rivera’s books paint a picture of what happens when things go down the toilet that can make a fun introduction to the idea of wastewater treatment. Here are our favorite lesson plans for Um, Mommy, I Think I Flushed My Brother Down the Toilet and Um, Mommy, I Think I Flushed My Brother Down the Toilet Again.

Real and Imaginary

Can people really get flushed down a toilet? Is there really a Yuck Kingdom? Certainly not. But there are things about the stories that ring true: older siblings can love their younger siblings and also find them maddening, kids can try to manipulate parents, and people can band together to stand up to something scary.

Have students list the real and imaginary things in the story.

Then study wastewater treatment and compare the reality with the imaginary Yuck Kingdom:

Have students look at these interactive resources and identify the things that are the same in all of them and the things that are different. Are there any parts of Yuck Kingdom that are like real sewage treatment?

Have students draw a line down the middle of a sheet of paper or poster board. Have them draw a scene from Yuck Kingdom on one side and from a real wastewater treatment plant on the other. Label them “Real” and “Imaginary.”


The book has lots of groups of rhyming words. Have students write the words on word cards and sort them into rhyming groups.  Have students find the parts of each group that are the same and the parts that are different. Find the groups where the same sound is spelled in different ways and those where the rhyming sound is spelled in the same way each time.

  • shaking
  • quaking
  • fumbled
  • tumbled
  • jumbled
  • twirled
  • swirled
  • curled
  • sluch
  • gush
  • mush
  • flush
  • blush
  • swaying
  • fraying
  • graying
  • rusty
  • musty
  • dusty
  • old
  • cold
  • mold

Some of the groups of rhyming words include made-up words. Find groups of words like these and have students divide the real words from the imaginary ones:

  • crying
  • mying
  • rying


At one point, the young heroine of the story says this about her little brother: “He was a pain, but he was my pain.” Author Jeff Rivera has 12 neices and nephews, so he knows what it’s like to have little brothers and sisters. Ask how many students have younger siblings. Create a list of the things they do that make them a “pain.” Then discuss what’s great about having brothers and sisters.

Some students may not have siblings. Ask whether they have similar experiences with a pet, friend, or relative.

Falisha doesn’t want her mommy to tell her daddy what she has done. She’s able to make things right, and we don’t see her getting in trouble with her dad, or having more than a scolding from her mom. Why do kids get in trouble with their parents? Is it important to make things right when we’ve done something we shouldn’t?

How does Falisha make things right with her brother? How does she make things right with her  mother?

Ask students whether they think Falisha and Jesse will get into trouble again in the future. Have them write a story of their own starring themselves and their sibling, pet, or friend.
