2nd Grade Thanksgiving Rounding
Second graders at Trevvett Elementary have been learning about Thanksgiving in Social Studies (SOL2.5h) and how to round two-digit numbers to the nearest ten in Math (SOL2.1d). Today students in Ms. Fletcher’s class created Google slideshows featuring Thanksgiving foods rounded to the nearest ten. First, we discussed their favorite Thanksgiving foods and why we might want to round the amounts. Rounding makes numbers easier to remember and use. It also helps with estimating. We reviewed how to round numbers down (if the ones place digit was 0, 1, 2, 3 or 4) and how to round numbers up (if the ones place digit was 5, 6, 7, 8 or 9). Then, we opened a blank Google slideshow and chose a theme. We typed a title and our name in the text boxes on the first slide, and I showed the students how to add another slide with the + button. We chose the “Big Number” slide template. In the smaller text box, the students typed a sentence telling how many items of a particular Thanksgiving food they had. They could choose any two-digit number they wanted, as long as it wasn’t already rounded. We typed the rounded number in the big text box. Since we wanted our classmates to solve our problems, I showed them how to add a transition to the number so it faded in later, revealing the answer only after the problem had been solved. Finally, we used the built-in Google image search to add a picture of the food. The students shared their slideshows on Schoology, but you can see them all here.
