Pre-K-2
Students explore the numbers 15 and 16. They make and decompose sets of size 15 and size 16, write the numerals 15 and 16, and compare other sets to sets of size 15 and size 16.
Pre-K-2
Students construct sets up to size 18, write the numerals 17 and 18, and model 17 and 18 with bean sticks, cubes, and ten frames.
Pre-K-2
Students explore sets of 19 and 20. They count up to 20, construct and decompose sets up to 20, and record the decomposition.
Pre-K-2
In this lesson, students are encouraged to discover all of the combinations for a given situation. Students apply problem-solving skills (including elimination and collection of organized data) to draw their conclusions. The use of higher-level thinking skills (synthesis, analysis, and evaluations) is the overall goal.
Pre-K-2
Students are introduced to the concepts of greater than, less than and equal to
by observing quantities and making comparisons. Using various
instructional materials such as modeling clay, buttons, beans, and
cotton balls, students create amounts to compare using the open-mouthed
fish. Depending which fish is chosen, the fish cut-out (with its mouth
open) represents either greater than or less than. For equivalent amounts, a clam cut-out represents equal to.
This introductory lesson can be assessed through visual observation
and verbal questioning. A group size of 3 – 6 students per group is
optimal.
Pre-K-2
Students build upon their understanding of
greater than,
less than, and
equal to
by observing quantities and making comparisons using various
instructional materials. The fish cut-out, with its mouth open,
represents the greater than or less than symbol; the clam cut-out
represents the equal to symbol. Using fish lips as a transition point,
students will apply their understanding of
greater,
less, and
equal to the standard symbols (>, <, =) as you introduce symbolic notation at a developmentally appropriate level.
Pre-K-2
Students learn their first basic addition facts as they make the
connection between counting and finding one more than a number.
Students will manipulate frogs on a number line to represent adding 1
to a number.
Pre-K-2
Students review numbers 1 to 10 by counting the number of letters in their names and their classmates' names. They also write and order numbers. The class compiles students' finished product in a class book.
Pre-K-2
Students represent number eight in writing and with a variety of manipulatives. They will construct sets of 8 by cutting 8 strips of paper and counting 8 pretzel sticks that represent spider legs. They will also use 8 plastic spiders to show 8 with a ten frame and count on from a given number to make 8.
Pre-K-2
In this lesson, students will play the role of a consumer as they learn how to use different combinations of coins to make money amounts up to 25 cents. Students will earn money and save it in their piggy banks until they have the exact amount to purchase an item of their choice.
