This short video and interactive assessment activity is designed to teach second graders about fluency in subtraction (numbers up to 20).
This short video and interactive assessment activity is designed to teach second graders about selecting the correct subtraction sentence.
This short video and interactive assessment activity is designed to teach second graders about addition: selecting the correct sentence.
This video and accompanying interactive assessment practice was designed to teach completing the subtraction sequence to first graders.
This task gives children an opportunity to subtract a three-digit number including a zero that requires regrouping. The solutions show how students can solve this problem before they have learned the traditional algorithm.
What we like about this task
Mathematically:
Addresses standards: 4.OA.A, 4.NBT.B, 4.OA.A.3, 4.NBT.B.6, MP.1, and MP.6
Requires students to understand the meaning of the quotient and remainder in order to solve problems in a real-world context
Addresses content across two major clusters (4.OA.A and 4.NBT.B) within the grade, specifically 4.OA.A.3 and 4.NBT.B.6
Requires students to interpret what is being asked and perform extensive calculations (MP.1) accurately and efficiently (MP.6)
In the classroom:
Offers opportunities for students to use strategies based on place value, properties of operations, and/or the relationship between multiplication and division to solve division problems
Provides repeated practice of multi-digit division and can be easily altered to allow for repeated use throughout the year
Allows for small group, partner, or individual work
This task requires students to add tenths and hundredths.
The purpose of this task is to help students see the connection between aÖb and ab in a particular concrete example. The relationship between the division problem 3Ö8 and the fraction 3/8 is actually very subtle.
This task addresses the division problem 4Ö1/3.
This task provides a context for performing division of a whole number by a unit fraction. This problem is a "How many groups?'' example of division.
Students play a game in pairs to read and recognize numbers using a 100 chart.
