How Big is a T-Rex Part 2
Friends work togther to build half meter long cube sticks.
I have some awesome learning to share from Wednesday. Wednesday morning, our class resumed our conversation on how to figure out how big our T-Rex was in real life. Several friends showed us how they had figured out how to mark a half meter by creating sticks of unifix cubes that were 50 cm long. We knew it was important to have this measurement, but we weren’t sure what to do next. We decided to take a closer look at our picture we were working from with the scale. We re-read that 1cm = .5 meters. Lucas asked, “Well how many centimeters is the picture?” Beatrice and Ayden knew, “21!” Then Lucas suggested, “Let’s make 21 sticks and lay them out. That’s how big!” Friends agreed that this would be the best way to represent our T- Rex. They demonstrated teamwork as the entire class enthusiastically began building sticks of equal lengths. Friends problem solved on how to check to make sure the sticks were equal. Some chose to re-measure them with a ruler, some compared them to others, some insisted on counting them each time and made sure they each had the same amount. When we finally had 21, we had a decesion to make. “What now?”
Teamwork!
Addie looks down the row, its getting longer!
Going off of Lucas’ suggestion, friends began taking turns connecting each of the pieces to create one, long line. The kids were paitient as we fixed breaks and troubleshooted directional problems. The cubes began to extend beyond our carpet area, past our word wall, and beyond. Miles enthusiastically predicted, “Its going to go out of the room! Its so big!” And Miles was right, our T-Rex ended up being SO big that it extended out of the classroom. WOW! After admiring our work in the morning, we decided to switch out the breakable cubes for something a little more permanent- tape. We laid down tape in place of the cubes to mark how long the T-Rex was and had fun decorating it with T-Rex-es and dinosaur words. Make sure you come check it out next time you are at school!
Longer!

Right out the door!
