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
Students compare and sort rectangles and special rectangles called squares learning to distinguish between the two using their attributes. They will use manipulatives to form squares and rectangles. They will also identify and take pictures of squares and rectangles around school and make a class book.
Pre-K-2
Go on an exciting measurement hunt around the classroom in search of items that are longer than, shorter than, and the same size as their piece of yarn. Pairs of students compare the length of their piece of yarn to objects around the classroom. They find and record at least one object that is longer than, one that is shorter than, and one that is the same size as their piece of yarn.
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.
Pre-K-2
In this lesson, students encounter the magical effect of reflection as they use a mirror to visually experience the concept of doubling quantities. This experience focuses student’s attention to using doubles as a strategy to make number operations easier, specifically addition. Literature is used as an introduction to provide a connection and motivation, a game is used for discovery and practice, and writing is used as closure to this lesson.
Pre-K-2
Your home team can set the stage for students to make math connections. Students will record wins and losses in different formats to discover connections between many of the concepts taught earlier in the year. This lesson will provide daily and weekly practice with patterns, addition and subtraction equations, number models and math communication.
3-5
Project this lesson on a whiteboard and watch your students “number line dance” their way to fluency in estimation of products. The lesson is scaffolded to start students finding basic multiplication facts on a number line and ends with students estimating four digit products on a number line. Use the lesson to teach estimation of products or as a culmination of your own estimation of products lesson.
Pre-K-2
Students search for hidden ducks in the classroom without collecting them and design their own method for keeping track of what they find. Discussion follows to compare methods used (tallies, numbers, dots, etc.) It would be fun to use this in the spring as an alternative to an egg hunt.
3-5, 6-8
If a tree could talk, we could ask it how old it is. Here is a mathematical way to estimate the age of your schoolyard trees. Students will measure circumference of trees in order to find diameter and calculate age of local trees using a growth rate table.
6-8, 9-12
Use tiles to represent variables and constants, learn how to represent
and solve algebra problem. Solve equations, substitute in variable
expressions, and expand and factor.
