Illustrative Mathematics K-5 MathTM is an IM Certified product providing trusted, highly rated materials to ensure students thrive in mathematics. Each Illustrative Mathematics lesson has four phases, from pre-unit practice modules to cool downs, focusing students’ attention on definitions, notations, and graphical conventions contributing to the development of real numbers.
The big ideas in
Have you ever wondered about the letters and words we use in talking and writing? What did people do before there were letters? Why are there only 26 letters in English? Often you are unaware that your questions drive your curiosity and exploration into language and communication. In this unit, your job is to decipher (figure out) the patterns, similarities, and differences of letters, word families and origins, sounds, and languages. Why are there so many languages in our world? Human language is unique and may help you to think in a different way as you explore the amazing variety o
The Teacher Resource Package includes the Hint & Think Beyond Cards and Word Wall Cards.
Hint and Think Beyond Cards – Designed to challenge students who demonstrate mastery of each unit’s concepts and objectives, these cards encourage students to expand their knowledge by using more complex reasoning.
The Student Mathematician’s Journal allows students to explore simulated or real-life problems and help them to think, write, and read like mathematicians. It encourages students to reflect on what they have learned in each lesson, think deeply about mathematics, and communicate in writing on worksheets.
In this unit, students explore our numeration system in depth and discover a stone wit
In this unit, students are introduced to ratios, rates, proportional reasoning, similarity and congruence. Students explore ratio as a comparison of two quantities. They discover that if the ratio between the corresponding side lengths and angle measures of two figures is 1:1 (i.e., the measures are identical), then the geometric figures are congruent. They learn that for two figures to be similar, their corresponding side lengths must be in proportion and their corresponding angles must be congruent. Students also explore the relationship between congruence and similarity, learning that al
On June 7, 2114, the Earth Survey Ship Aurora disappeared near Jupiter, leaving no trace behind as to its destination, nor as to the fate of its crew. On July 20, 2134, the ESS Aurora returned, carrying with it all the horrors of the void, but also with the promise of information gathered from its ghastly inter-dimensional and time travels. It falls to the people of a secret United Earth agency, the OAR, to negotiate for what the ghostly vessel offers, and the Aurora always demands a sacrifice in return.
