Kindergarten One Less Worksheet: Yo-Yos, Horns and Umbrellas to 5

Take one cookie off a plate of five and most five-year-olds know at once that something changed, yet saying "now there are four" takes a little more. This kindergarten one less worksheet works on that step. Each of the three rows starts with a model: 5 yo-yos, then 4 yellow horns (the page calls them trumpets), then 3 umbrellas. Below each model, three boxes hold different amounts, and your child ticks the box that has one less. The PDF has two pages, the worksheet and its answer key.

Why one less matters before subtraction

Knowing that four comes just before five is a big idea in disguise. It means the child sees numbers as a line, where each step back takes away exactly one. That is the heart of number sense, and it prepares subtraction long before any minus sign.

This page makes the idea concrete. The model row stays in view, so your child can count it, then count each box and compare. For example, the umbrella row asks, "Which box has one fewer than three?"

The page also keeps every set small, with numbers up to 5 only. As a result, the effort goes into comparing quantities, not into long counts. One step back.

At the table: the row of horns

Begin with the yo-yos. Ask your child to count the five in the model, then say, "Now find the box with one less." Let them touch each yo-yo in each box.

The horn row holds a trap, because its first box has four horns, exactly like the model above it. A child who looks for a match may tick it right away. Instead of correcting, ask, "Is that one less, or the same?" Then count the model again together.

On the umbrella row, some children tick the box with four, mixing up more and less. Hold up three fingers, fold one down and ask, "How many now?"

Once you finish, compare the ticks with the answer key on the second page.

Cookies, umbrellas and five little ducks

One less shows up all day long. At snack time, put five crackers on a plate, eat one together and ask, "How many are left?" Do it again until the plate is empty.

By the door, line up the family umbrellas or shoes, and take one away while your child hides their eyes behind their hands. Ask, "What changed?"

The song "Five Little Ducks" is built on this idea: one duck stays away each verse, so the number drops by one every time. While you sing, hold up five fingers and fold one down per verse. Then switch and sing it counting up, which turns it into a game of one more, one less.

When you finish the page, praise the checking: "You counted the model every time before you ticked."
