A Fountain Spout for Quince Hollow: A Grade 1 Height Worksheet

A grade 1 worksheet where students order three drinking fountain spouts by the height of their water arc in cubes and pick the spout that fits a first grader.

Objectives

  1. Students will order three water arcs from lowest to highest using cube measurements.
  2. Students will compare two arcs indirectly by using a third arc.
  3. Students will explain how the shape of a spout changes where the water goes.

Vocabulary

Water pressure
Water pressure is the push that makes water flow out of a faucet or hose. In town water systems, the push comes from pumps and from water stored high up in tanks and towers.

Teacher overview

The hallway drinking fountain at the make-believe Quince Hollow School was built for older students, so the water arc rises well above where a first grader's mouth reaches and the youngest students end up leaning in awkwardly. A parent volunteer tried three replacement spouts and measured the top of each water arc by stacking snap cubes beside it. This worksheet gives students those three cube heights and asks them to put the spouts in order, compare two of them through a third, and choose the one that comes closest to a first grader's height at the fountain. The measuring unit is deliberately the cube rather than the inch, which keeps the comparison inside first-grade measurement work.

Answer Key

  1. Answer: Spout B.
    Spout B went 7 cubes high and Spout A went 3 cubes high, and 7 is more than 3.
  2. Answer: A, C, B.
    Ordered from lowest to highest, that is Spout A at 3 cubes, Spout C at 4 cubes, and Spout B at 7 cubes.
  3. Answer: Yes.
    Spout A is lower than Spout C, and Spout C is lower than Spout B, so Spout A must also be lower than Spout B. Students may check with the numbers, since 3 is less than 7.
  4. Answer: 3 cubes.
    7 − 4 = 3, so Spout B's water went 3 cubes higher than Spout C's water.
  5. Answer: 4 cubes.
    7 − 3 = 4, so Spout B's water went 4 cubes higher than Spout A's water.
  6. Answer: 7 cubes.
    3 + 4 = 7 cubes when the two heights are put together.
  7. Answer: Spout B.
    Spout B is 7 cubes, which is 1 cube away from 6. Spout C is 4 cubes, which is 2 cubes away, and Spout A is 3 cubes, which is 3 cubes away.
  8. Answer: The bend turns the water upward so it arcs toward the child's mouth.
    Accept any wording that connects the bent shape to sending water up and out rather than straight down into the basin.
  9. Answer: Answers vary.
    Accept any drawing with a stated cube height and a reason tied to a drinker's height, such as picking 6 cubes so a first grader does not have to stretch or bend.

Differentiation

Support (below grade level)

Give these students a strip of paper with 7 squares drawn on it and loose snap cubes so they can build each arc height before answering. Shade the squares for Spout A, Spout C, and Spout B in three colors so items 1, 4, and 5 become a matter of lining the towers up side by side.

Extension (above grade level)

Ask these students to find a spout height that would sit exactly between Spout A and Spout C and explain why no whole cube number works there. They can then design a fountain with two spouts at different heights and label who each one is for.

ELL supports

Post a picture card for each spout showing a cube tower of the matching height beside a curved arrow for the water, so items 1 through 7 can be answered by pointing before writing. Pre-teach four words with gestures: high, low, bend, drink. Allow items 8 and 9 to be answered with a labeled drawing.

Extensions

Measure the real fountain in your hallway with a stack of cubes or a strip of adding-machine tape, then measure the height of a first grader's mouth the same way and compare the two strips. Students can write one sentence to the office saying whether the fountain fits the youngest students at the school.
