2012 Revised TEKS K.2(I) compose and decompose numbers up to 10 with objects and pictures. 1.3 (C) compose 10 with two or more addends with and without concrete objects; 1.3(D) apply basic fact strategies to add and subtract within 20, including making 10 and decomposing a number leading to a 10; 2.4 Number and operations. The student applies mathematical process standards to develop and use strategies and methods for whole number computations in order to solve addition and subtraction problems with efficiency and accuracy. The student is expected to: 2.4(A) recall basic facts to add and subtract within 20 with automaticity;
Common Mistakes Be sure to not confuse bar graphs and histograms. Although they resemble each other their details and uses are different. Bar Graphs are to be drawn with blank space between the bars to separate the items being compared. Histograms are drawn with no spaces, to show the equal-width classes.
Unit 3: Numeration Take this time to read and study the Unit 3 IFD. Discuss at your table instructional activities you do to support a deeper understanding for students in regard to our number system.
Questions to Consider Can students decompose numbers by place value other than just a single digit? (How many tens make up the number 370?) Do students understand the equivalence of one group and the discrete units that constitute it? How do students use the 100s chart to solve problems? Can students employ strategies of using our number system both with and without the use of a 100s chart equally as effectively? Can students generalize the pattern of tens to count and build numbers over 100?

Unit 4: Number Lines Students must be able to count by tens on and off the decade and jump across tens! 1.5) Algebraic reasoning. The student applies mathematical process standards to identify and apply number patterns within properties of numbers and operations in order to describe relationships. The student is expected to 1.5(C) use relationships to determine the number that is 10 more and 10 less than a given number up to 120
Questions to Consider Do students have a clear sense of magnitude of numbers as they relate to each other our of the rote sequence? Do students recognize the relationship between a quantity and its location? Do students notice both the sequence of the numbers on a number line and the intervals used so that they can use the number line flexibly?
Money Read through the specificity regarding coins in Unit 4, then as a group provide a nonlinguistic representation on chart paper to define the overall understanding students should have upon completion of the instruction of Unit 4. Be sure your representation meets the bundled specificity listed within your Unit 4 IFD.
