"This game gives children practice with adding and subtracting ones and tens. Using a special die, two 0 99 charts, and two markers, children play in pairs. During the course of a game, they calculate between 20 and 30 addition and subtraction problems." (from Math Solutions Professional Development)

Type: Educational Game

A printable hundreds chart featuring a 10x10 table numbered 1 to 100. (found on Illuminations website under "Trading for Quarters")

Type: Educational Software / Tool

Students use a counting strategy to find the difference between two numbers.

Type: Formative Assessment

Students are encouraged to use Counting On to solve Add To (Result Unknown) word problems.

Type: Formative Assessment

Students are asked to write equations that correspond to counting strategies used in word problems.

Type: Formative Assessment

Students are guided to use counting to find the sum of two numbers.

Type: Formative Assessment

The learner will relate counting to addition and subtraction by using the strategies "Counting Up" and "Counting Down". This lesson engages students through the use of short videos, manipulatives, literature, and games

Type: Lesson Plan

This STEAM (Science, Technology, Engineering, Art, and Math) lesson has been designed around a Model-Eliciting Activity.

The Flower Power MEA provides students with an real world problem in which they must work as a team to design a plan to select the best flower arrangement for a special event. The resource was primarily designed as an MEA so the time and teacher instructions are based on the MEA format. The additional activities will take several hours of instruction but include watching and discussing a video about the parts of plants, reading a book, and discussing the art in the book as well as additional art by the book author/illustrator.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.

Type: Lesson Plan

In this open-ended question, students in teams will make decisions about how to rank vegetables to plant on a farm. The students' decisions will be based on various criteria.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem, while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought process. MEAs follow a problem-based, student centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.
