This short video and interactive assessment activity is designed to teach fourth graders about representing numbers in expanded form i.

This short video and interactive assessment activity is designed to teach fourth graders about number riddles (numbers up to 100,000).

This short video and interactive assessment activity is designed to teach fourth graders about place value problems involving money.

The focus of the Adding Up to Four Two-Digit Numbers intervention is adding two-digit numbers with base ten blocks.There are four phases to this intervention. Phases 1 to 3 focus on adding 2 two-digit numbers and progress from no regrouping to regrouping in both the ones and tens. Phase 4 focuses on adding 3 or 4 two-digit numbers.

This instructional task requires students to figure out word problems that require thinking in base 10.

The focus of the Building and Writing Three-Digit Numbers intervention is the number of hundreds, tens, and ones that make a three-digit number. It has three phases. Phase 1 is an introduction to the use of place value charts, base ten blocks, and number cards. Phases 2 and 3 move from three-digit numbers that have zero tens and zero ones to all kinds of three-digit numbers.

In this task students determine the number of hundreds, tens and ones that are necessary to write equations when some digits are provided. Students must, in some cases, decompose hundreds to tens and tens to ones.

The focus of the Comparing Two-Digit Numbers intervention is to use base ten blocks to help compare two two-digit numbers and use the appropriate symbol to record the result.

The focus of the Comparing Two Three-Digit Numbers intervention is using base ten blocks to compare the numbers and then using symbols >, <, =, to record the results of the comparison.

In this task students are required to compare numbers that are identified by word names and not just digits. The order of the numbers described in words are intentionally placed in a different order than their base-ten counterparts so that students need to think carefully about the value of the numbers.

Students who work on this task will benefit in seeing that given a quantity, there is often more than one way to represent it, which is a precursor to understanding the concept of equivalent expressions.

This is an instructional task related to deepening place-value concepts. The important piece of knowledge upon which students need to draw is that 10 tens is 1 hundred.

This collection of 6 games develops place value, operation sense and fluency, estimation, and strategic thinking. It is played on paper with a 6- or 9-sided die (printable pdf game sheets included). Players choose a game grid with empty cells representing the digits of a computation (addition, subtraction, multiplication, or division). They take turns rolling a die and placing the resulting number in a cell on their own grids. The goal is to create a sum/difference/product/quotient that is closest to a target number. Variations include using a decimal point and scoring options. Teachers' Notes include suggestions for introducing the game, discussion questions, support suggestions, and a link to a more challenging extension (Countdown, cataloged separately).

This task helps students understand the relationship between digit placement and the value of a number.

The focus of the Find the Next Number from 11-99 intervention is saying and writing the next number up to 99. It has two phases that use base ten blocks. Phase 1 focuses on the next number within a ten. Phase 2 focuses on the next number over the transition over ten, like 59 to 60.

The focus of the Find the Number Before intervention is saying and writing the number that is before or one less than a number up to 99. It makes use of a place value chart and base ten blocks.
