Problem Solving16:36
Problem Solving#217:10
Problem Solving#318:51
3rd grade problem solving with weekly fruit counts, hand counting, kangaroo leaves, apple banana exchanges, and balancing sums in two boxes.
Problem Solving#49:41
Problem Solving#56:05
Explore consecutive digits and missing digits in 4-digit numbers by place value, then solve a fruit allocation puzzle to ensure everyone gets a different fruit, with Ben getting apples.
Problem Solving#614:04
Solve problem solving #6 by balancing weights on both sides and analyzing a honeycomb puzzle, then compute dimensions to find the area of the shaded rectangle.
Problem Solving#713:08
Problem Solving#811:44
Analyze multi-step problem solving by calculating expressions and angles, such as a circle with 10 equal pieces and 360 degrees. Apply truth-teller pirate logic and elimination to deduce correct answers.
Problem Solving#912:22
Tackle grade-3 problem solving with step-by-step reasoning on questions 6–10, including counting stops and beaver-tree visibility puzzles, plus circles, triangles, and squares with clockwise turning logic.
Problem Solving#1014:15
Problem Solving#1112:23
Develop problem solving skills in math by exploring counting challenges, adding sums, and arranging pieces or digits. Learn to rotate or flip pieces, maximize sums, and compare different card combinations.
Problem Solving#129:53
Problem Solving#1314:36
Develop problem solving in 3rd grade math by counting on a 4 by 6 grid, using ink subtraction, recognizing patterns, and planning routes to maximize sums while visiting rooms once.
Problem Solving#1410:16
Explore problem solving strategies in 3rd grade math, including counting inked squares on a 4x6 grid, pattern-based basket arrangements, route planning avoiding colored squares, sequencing sticks, and maximizing path sums.
Problem Solving#1514:12
Develop problem-solving through left-turn routing puzzles, card swap challenges to sort sequences, and deducing shape values (square 6, triangle 4, circle 2) from row and column sums.
Fraction Identifying#166:12
Identify fractions by coloring blocks on a practice worksheet, learning fractions such as 1/3, 1/2, 2/6, and 4/10 through step-by-step examples.
Problem Solving#1611:21
18-Multiplying Fraction8:38
Learn how to multiply fractions by canceling common factors, simplifying first, and then multiply numerators and denominators for a quick answer.
19-Dividing fractions by fractions13:24
20-Convert decimals to fractions13:03
Learn to convert decimals to fractions using steps, multiply by 10 or 100 based on decimal digits, and simplify by canceling common factors to the simplest form.
21-Adding unlike fractions24:20
22-Subtracting unlike fractions24:20
Learn to subtract unlike fractions step by step by reducing fractions and finding the least common multiple of denominators, then compute the difference across 12 practice problems.
23-Convert-decimals-to-fractions19:22
Convert decimals to fractions and simplify them for 3rd grade math using common factors, illustrated with 0.82 becoming 41/50 and 0.4 becoming 2/5, along with practice questions and steps.
