Place Value Hockey is a fun educational game for kids to practice place value. There are 2 modes of play and 3 levels of difficulty. Modes of play: Identify Place Value & Type Numerals Difficulty: Level 1: ones to hundreds; Level 2: ones to millions; Level 3: ten thousandths to millions The game will show percentage correct and players get to take penalty shots when they get five correct in a row. You could use this resource as a formative assessment, game for kids to practice place value, or as a station in your math workshop.

This lesson was used with a tier 3 fourth grade intervention math group to help students to progress from counting by tens and ones to combining and separating by tens and ones without skip counting. I used this Illustrative Math lesson, https://www.illustrativemathematics.org/content-standards/tasks/2106, and modified it to meet the students' needs. I modified the lesson by doing only the activities in Part 3 and then extending this by modeling the equations, that matched the hundreds chart work, with base ten blocks. I also made sure students saw the pattern in adding ones and adding tens and encouraged the proper place value terms. For example, "4 + 3 = 7 so 4 groups of ten + 3 groups of ten = 7 groups of ten which is the same as 40 + 30 = 70." I then extended this by having students add numbers with tens and ones to number with tens and ones with and without regrouping and asked them to first model it on the hundreds chart and with base ten blocks and then do the addition without skip counting (first adding the tens and then the ones and then combine the results).

This task serves as a bridge between understanding place-value and using strategies based on place-value structure for addition.

Big Ideas: Rounding is an appropriate strategy for solving problems and estimating. Numbers can be decomposed and recomposed to add and subtract.
This lesson builds on student knowledge of place value of whole numbers less than or equal to 1000. This task uses a range of weights for endangered animals for students to apply rounding principles to make totals of 1000 and 2000 using addition and subtraction strategies. This builds conceptual understanding of rounding to build upon for practical use for problem solving using addition, subtraction, multiplication, and division.
Vocabulary: base-ten, expanded form, place value, accurate, complements, commutative property, partial sums

The purpose of this task is to help students understand composing and decomposing ones, tens, and hundreds. This task is meant to be used in an instructional setting and would only be appropriate to use if students actually have base-ten blocks on hand.

The brief video clips on this webpage illustrate the range of number sense exhibited by students in grades Pre K-2. In interviews, Cena and Jonathan, both age 7, and Rudy, age 9, demonstrate different levels of understanding number and place value concepts. The page includes discussion questions for each set of videos as well as concluding reflection questions.

Lesson objective: Apply knowledge of ways to name numbers. 
This lesson provides an opportunity for students to apply their knowledge and understanding of naming numbers to a mathematical situation. Students are asked to help the teacher complete her set of game cards by coming up with equivalent names for numbers. 
Key Concept students will use: 
Representing a whole number in different ways (including base ten numerals, number-names, and expanded form) does not change its value.
Skills students will use:
Understand that the three digits of a three-digit number represent the amount of hundreds, tens, and ones (Grade 2, Unit 6)Write three-digit numbers in expanded formWrite three-digit numbers in word formWrite three-digit numbers in standard form
Students engage in Mathematical Practice 7 (Look for and make use of structure) as they look for patterns in the way we name numbers to name numbers they have not seen before. 

I created this lesson using the place value cards found on Helping With Math, https://www.helpingwithmath.com/printables/flashcards/2nbt3-number-cards01.htm and was used with a tier 3 fourth grade intervention math group to help students understand place value in expanded algorithms for addition. First I asked students to mentally add two three digit numbers that did not include zeros. When students added them by place value I notated it on a white board using expanded form and pointed out how it matched the student's mental strategy. I then gave students additional problems and students used the place value cards to expand the numbers and then wrote the corresponding expanded notation algorithm on whiteboards. Students had a little difficulty using the cards when zeros were in the tens and ones place. We addressed misconceptions with zeros in place values.
