About foods of the Americas

Many foods eaten all over the world today were first grown by Native peoples of the Americas. Corn, squash and chili peppers were first grown in Mexico thousands of years ago; potatoes come from the Andes of South America, where Quechua and other Andean peoples still grow hundreds of kinds; peanuts and cacao (the bean chocolate is made from) also come from South America. In the Great Lakes, Anishinaabe (Ojibwe) families still gather wild rice from lakes by canoe in late summer, and cranberries and sunflowers are North American plants too. The places on these pages come from Smithsonian, university and tribal sources.

How to Use This Pack

Five pages of 1st and 2nd grade math with foods first grown in the Americas. Page 1 shows where nine foods were first grown, then a harvest table: students count each food and add the three foods from each place. Page 2 is a picture graph of a class's favorite foods with six questions. Page 3 adds two baskets within 20. Page 4 lines up two rows: circle the row with more and write the subtraction. Page 5 has six word problems within 100. The first problem on each page is a worked example.

In the Classroom

Start with page 1's three boxes: ask which foods the class has eaten this week, and where each was first grown. Crossing off each picture on the harvest table as it is counted keeps the counts right.

At Home

Look in the kitchen for foods from these pages (corn, potatoes, tomatoes, beans, peanuts, chocolate) and sort them by where they were first grown.

Tips for Success

  • Cross off each picture as you count it
  • Add the two biggest numbers first, or look for a 10
  • Line the rows up to see how many more
  • Read a word problem twice before you solve it

Common Core Standards Alignment

This pack supports the following Common Core State Standards for Mathematics:

  • 1.OA.A.2 Solve story problems where three numbers are added together for a total of 20 or less.
  • 1.OA.C.6 Add and subtract to 20, working fluently within 10, with strategies like counting on, making ten, fact families and doubles plus one.
  • 1.MD.C.4 Sort and show data in up to three groups, then answer questions about the total, each group's count, and how groups differ.
  • 2.OA.A.1 Solve one- and two-step story problems with sums and differences up to 100, with the unknown in any position, using drawings and equations.
  • 2.OA.B.2 Add and subtract to 20 quickly using strategies done in the head, and by year's end instantly recall every sum of two single-digit numbers.
  • 2.NBT.B.6 Find the sum of two, three or four two-digit numbers using place value and properties of addition.
  • 2.MD.D.10 Make picture and bar graphs (one unit per square or picture) for up to four categories, and answer joining, separating and comparing questions from them.
