 Lesson Plan ID: 33034 Title: Let's Go Shopping Overview/Annotation: Students will be given a task card stating how to spend a certain amount of money. Students must look through sale papers, find the items to purchase, add the totals, multiply quantities, subtract from the total, and write a check to purchase the items.This is a College- and Career-Ready Standards showcase lesson plan.
Associated Standards and Objectives
Content Standard(s):
 Mathematics MA2019 (2019) Grade: 4 7. Read and write multi-digit whole numbers using standard form, word form, and expanded form. Unpacked Content Evidence Of Student Attainment:Students: When given a number in one form (base-ten numerals, words, expanded form), identify the number in another form. Note: Expectations are limited to whole numbers less than or equal to 1,000,000.Teacher Vocabulary:Base-ten numerals Expanded form Expanded notation Standard form Word form Place value Thousands period Ones periodKnowledge:Students know: the relationship among places in a number and place values.Skills:Students are able to: Read numbers 1 to 1,000,000 based on place value understanding. Write numbers using base-ten numerals. Write numbers using expanded notation. Write numbers in word form.Understanding:Students understand that: The same quantity can be represented with mathematical models, words, and expanded form based on the place value of the digits. The value of a digit in a multi-digit number depends on the place value position it holds.Diverse Learning Needs: Essential Skills:Learning Objectives: M.4.7.1: Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits using >, =, and < symbols to record the results of comparisons. M.4.7.2: Read and write numbers to 1000 using base-ten numerals, number names, and expanded form. M.4.7.3: Convert a number written in expanded notation to standard form. Prior Knowledge Skills:Define greater than, less than and equal to. Compare two two-digit numbers based on meanings of the tens and ones digits, recording the results of comparisons with the symbols >, =, and <. Arrange two-digit numbers in order from greatest to least or least to greatest. Identify zero as a place holder in two-digit and three-digit numbers. Model using >, =, and < symbols to record the results of comparisons of two two-digit numbers. Select numbers on a number line that are more than, less than or equal to a specified number. Match the words greater than, equal to and less than to the symbols >, =, and <. Determine the value of the digits in the ones and tens place. Identify sets with more, less or equal objects. Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction. Number & Operations in Base Ten. Use place value understanding and properties of operations to add and subtract. Alabama Alternate Achievement Standards AAS Standard: M.AAS.4.6 Compare whole number values to 50 using symbols (e.g., <, >, =). Mathematics MA2019 (2019) Grade: 4 10. Use place value strategies to fluently add and subtract multi-digit whole numbers and connect strategies to the standard algorithm. Unpacked Content Evidence Of Student Attainment:Students: Use place value strategies and properties of operations to build procedural fluency and understanding of the standard algorithm for addition and subtraction. Note: Expectations are limited to whole numbers within 1,000,000.Teacher Vocabulary:Addition Subtraction Standard algorithm Place value Decompose Compose Fluently Multi-digit Strategy Difference SumKnowledge:Students know: a variety of accurate and efficient strategies to find sums and differences and use them when appropriate.Skills:Students are able to: Use place value strategies to add and subtract multi-digit numbers. Use the standard algorithm for addition and subtraction and connect strategies to the standard algorithm. Understanding:Students understand that: There are a variety of strategies, models, and representations for solving mathematical problems with addition and subtraction. Efficient application of computation strategies is based on the numbers and operations in the problems. The steps used in the standard algorithm for addition and subtraction can be justified by using the relationship between addition and subtraction and the understanding of place value. Diverse Learning Needs: Essential Skills:Learning Objectives: M.4.10.1: Multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 x 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. M.4.10.2: Multiply single-digit numbers. M.4.10.3: Recall basic multiplication facts. M.4.10.4: Apply concepts of multiplication through the use of manipulatives, number stories, skip-counting arrays, area of a rectangle, or repeated addition. Prior Knowledge Skills:Define the commutative and associative properties of addition and subtraction. Subtract within 100 using strategies and algorithms based on the relationship between addition and subtraction. Subtract within 100 using strategies and algorithms based on properties of operations. Subtract within 100 using strategies and algorithms based on place value. Add within 100 using strategies and algorithms based on the relationship between addition and subtraction. Add within 100 using strategies and algorithms based on properties of operations. Add within 100 using strategies and algorithms based on place value. Recall basic addition and subtraction facts. Define regrouping, total, sum, difference and solve. Add and subtract two two-digit numbers with and without regrouping. Determine the value of the number in the ones, tens, hundreds and thousands place using concrete models or drawings and strategies based on place value. Match the number in the ones, tens, hundreds and thousands position to a pictorial representation or manipulative of the value. Model written method for recording horizontal and vertical addition and subtraction problems. Represent two- and three-digit numbers with multiple models. Examples: models—base ten blocks, number lines, linking cubes, straw bundles. Recall single-digit addition and subtraction facts. Add and subtract within 20, e.g., by using objects or drawings to represent the problem. Alabama Alternate Achievement Standards AAS Standard: M.AAS.4.11 Add and subtract one and two-digit numbers up to 49 with regrouping using concrete manipulatives and visual models.
