 Topic D builds on the work of Topic B, again providing opportunities for children to solve addition story problems while taking a step forward by representing the objects in the story with fingers,...

 In Topic C, children shift focus to subtraction stories with numbers 1 to 5, again acting them out, using fingers, manipulating objects, drawing, and counting pictorial representations to model the...

 Topic B marks an exciting point in PreK children’s math learning as they begin to explore addition of numbers to 5 through story problems. They build on the comparison work of Module 4, so that "...

 Children have been working with the numerals 15 since Module 1 and the number 0 since Module 3. Throughout the year, they have had many opportunities to match a number of objects with a prewritten...

 In Topic G, students compare quantities using numerals by using the counting and matching strategies they have practiced throughout the module. Connecting both sets to a numeral and indirectly...

 In Modules 1 and 3 students did extensive work to develop understanding of numbers to 10. The first half of Module 4 was dedicated to comparison of measurement. Topic F brings together this work...

 So far, PreKindergarten students have done a lot of onetoone counting, have compared measurable attributes, and have identified the first and last in a group of objects. Topic E brings these...

 Topic D begins by building upon the work of Module 1 by having students count 5 bears in a scattered configuration while identifying the first and last bear counted (PK.CC.6). This concept is a...

 In Topic C, the concept of volume and the vocabulary used to describe and compare it (i.e., big, small, more, and less) are discussed. This is perhaps the most familiar to young children, compared to...

 Topic B begins with children using correct vocabulary, heavy and light, to describe weight (again, as opposed to big and small). In Lesson 6, students choose an object from a prepared bin of heavy...

 In Topic A, students use correct vocabulary, tall or short, to describe length. Because PreKindergarten students entering school might describe most objects as big or small, Lesson 1 helps students...

 Students study the basic properties of twodimensional and threedimensional space, noting how ideas shift between the dimensions. They learn that general cylinders are the parent category for...

 Students begin their work with 3dimensions by first developing a stronger sense of area in two dimensions. They find approximated areas of curved figures by “squeezing” them between inscribed and...

 Students link their understanding of similarity and relationships within similar right triangles formally to trigonometry. In addition to the terms sine, cosine, and tangent, students study the...

 The focus in Topic D is similarity within right triangles. Students examine how an altitude drawn from the vertex of a right triangle to the hypotenuse creates two similar subtriangles. Students...

 Students learn what it means for two figures to be similar in general, and then focus on triangles and what criteria predict that two triangles will be similar. Length relationships within and...

 Students study and prove the properties of dilations.

 Students revisit what scale drawings are and discover two systematic methods of how to create them using dilations. The comparison of the two methods yield the Triangle Side Splitter Theorem and the...

 Conclusions are drawn based on data from a statistical experiment. Simulation is used to explore whether an oberved difference in group means is significant. Published reports based on statisical...

 The purposes of and differences among observational studies, surveys, experiments are explored along with how randomization relates to each. Data from random samples are used to estimate a...

 Smooth curves are used to model given data distributions, eventually using the normal distribution to model data distributions that are bell shaped and symmetric. Tables and technology are used to...

 Chance experiments, sample space, and events such as unions, intersections, and complements are explained. Probabilities of unions and intersections are calculated using data in twoway tables and...

 Topic E is a culminating series of lessons driven by MP.4, Modeling with Mathematics. Students apply what they have learned about mathematical models and exponential growth to financial literacy...

 Topic D opens with a handson simulation and modeling activity in which students gather data and apply the analysis of Lesson 22 in Topic C to model it with an exponential function (ACED.2, FLE.5...
