First graders create clocks by adding hour and minute hands pointing to the given time. All times are to be written in 30-minute intervals.

Use a number line to demonstrate subtracting by tens. Learners "hop" backwards down a tens number line to complete subtraction equations. Several different ways to express the operation are included. 

Youngsters think about the length of different periods of time. They label the seven most common units of time measurement, then answer eight questions that have to deal with those same units of time. A good worksheet!

In this subtraction worksheet, students cross out the pictures in each set to complete the subtraction sentence. students write the number of pictures left in the 30 problems.

Class members predict and count how many items need to be cleaned up in class while skip counting by 10s. They estimate whether having each child clean up 10 items will be enough to get the room ready for the next day. Everyone counts...

Young mathematicians concentrate on learning to fluently count. Following the rules of the classic game Memory, children take turns flipping over cards in order to find pairs of numbers that cross a decade (e.g. 29 and 30). For younger...

Using a 100s chart or a number line with a pointer, work with your class to count up to 100 by ones and tens. As a part of daily instruction, prompt your kindergartners to chant count from 1 to 30. Move on to 1 to 50, and then from 1 to...

Students share a bowl of goldfish crackers. In this lesson on sharing, students see how a limited resource goes furthest when it is evenly shared. Students are allowed to take as many crackers as they would like, and then in contrast,...
