Teaching Science to ESL & First Grade Students: COMPARING & GROUPING OBJECTS (Same & Different)

Following the lesson on The Five Senses, students can compare and group objects.   Here are some activities:

  • Make sure students understand “same” and “different.” Have two objects that are exactly the same and one that is different (such as two math books and an English book, or two identical balls and one that is different, etc.)  Show the two objects that are the same and talk about how they are alike.  Then show two objects that are different and talk about the ways they are different.
  • Show two flowers that are not completely alike and talk about the ways they are the same (both are pretty, both smell good, both have stems, both have leaves, etc.) and ways they are different (one is shorter, they are different colors, etc.)  Talk about how we use our senses of look, smell, and touch when we’re comparing the flowers.
  • Explain to students there are different ways to compare things. Have a group of objects such as shells that the students can practice comparing and putting into groups such as big shells/little shells and then white shells/colored shells.  Other objects that you could use to compare and group would be different sizes and colors of seeds, various rocks, or different sizes and colors of marbles.
  • Have students compare their pencils.  Remind students there are different ways to compare things.  Have students with pencils longer than six inches line up on one side of the room.  Have students with pencils shorter than six inches line up on the other side.  Another comparison would be to have yellow pencils on one side and colored pencils on the other side.  Or pencils with erasers on one side and those without erasers on the other.
