Decimals | Review Lesson
A short, playful review lesson for Pre-K students to practice foreign-language number words while exploring the idea of decimals as "small parts" using whole numbers and picture models. The lesson uses repetition, movement, and visuals to keep it age-appropriate and engaging.
| Term | Definition |
|---|---|
| number | A word that tells how many. |
| decimal | A small part of a whole number, shown with a dot. |
| dot | A tiny mark used in numbers or pictures. |
| more | A bigger amount. |
| less | A smaller amount. |
Greet students in the target foreign language. Show number cards 0-5 and say each number word clearly. Invite students to repeat the words with you.
Repeat the greetings and number words. Point to or show fingers for each number.
Show a large visual with one whole shape and a second shape split into small parts. Say, "A decimal is a small part." Point to the dot in a decimal example and connect it to the idea of a small piece.
Watch, repeat the key word, and point to the dot with the teacher.
Hold up picture cards with dots or divided shapes. Say a foreign-language number word and have students repeat. Ask students to show the matching number with fingers or by clapping the count.
Repeat the number words, use fingers, clap, and point to the correct picture card.
Call out a number word or show a decimal picture. Students make a movement: stand tall for "more," crouch small for "less," or touch the floor when they hear the dot/decimal cue. Keep the pace quick and playful.
Respond with the matching movement and listen for the spoken word or visual cue.
Review the key idea: decimals show small parts. Say the number words one more time with the class. Praise effort and participation.
Repeat the key phrase and the final number words with the teacher.
End by chanting the key review phrase together: "Decimals are small parts!" Then have students show one finger and one dot with their hands to remember the idea.
