This I Have... Who Has..? game has 25 cards. It covers vocabulary words and definitions students should know for in 3rd to 6th grade. Words include: classification key, hypothesis, independent variable, dependent variable, constant, charts and graphs, metric, scientific prediction estimates, inference, conclusion, model, centimeter ruler/meterstick, graduated cylinder, balance scale, stopwatch, thermometer, millimeter/ centimeter/ meter/ kilomter, gram/ kilogram, milliliter/ liter, degrees celsius, observations, qualitative, quantitative, and experiment.
Directions for play: Cut out the cards. Give each student one card (or two if there are less than 25 students). Choose a student to start. He/she asks the question at the bottom of the card. Whoever has the answer says "I have ---" and then asks the question on the bottom of the card. This continues until it gets back to first card.
Use the plain version if you are just going to use it once and throw it away, or if you are going to give a set to each student to practice. You can also use it as an answer key.
Use the more visual version if you are going to laminate and use over and over again!
